| In the Linux kernel, the following vulnerability has been resolved:
media: iris: gen1: Destroy internal buffers after FW releases
After the firmware releases internal buffers, the driver was not
destroying them. This left stale allocations that were no longer used,
especially across resolution changes where new buffers are allocated per
the updated requirements. As a result, memory was wasted until session
close.
Destroy internal buffers once the release response is received from the
firmware. |
| In the Linux kernel, the following vulnerability has been resolved:
remoteproc: imx_rproc: Fix invalid loaded resource table detection
imx_rproc_elf_find_loaded_rsc_table() may incorrectly report a loaded
resource table even when the current firmware does not provide one.
When the device tree contains a "rsc-table" entry, priv->rsc_table is
non-NULL and denotes where a resource table would be located if one is
present in memory. However, when the current firmware has no resource
table, rproc->table_ptr is NULL. The function still returns
priv->rsc_table, and the remoteproc core interprets this as a valid loaded
resource table.
Fix this by returning NULL from imx_rproc_elf_find_loaded_rsc_table() when
there is no resource table for the current firmware (i.e. when
rproc->table_ptr is NULL). This aligns the function's semantics with the
remoteproc core: a loaded resource table is only reported when a valid
table_ptr exists.
With this change, starting firmware without a resource table no longer
triggers a crash. |
| In the Linux kernel, the following vulnerability has been resolved:
powerpc/smp: Add check for kcalloc() failure in parse_thread_groups()
As kcalloc() may fail, check its return value to avoid a NULL pointer
dereference when passing it to of_property_read_u32_array(). |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix signededness bug in smb_direct_prepare_negotiation()
smb_direct_prepare_negotiation() casts an unsigned __u32 value
from sp->max_recv_size and req->preferred_send_size to a signed
int before computing min_t(int, ...). A maliciously provided
preferred_send_size of 0x80000000 will return as smaller than
max_recv_size, and then be used to set the maximum allowed
alowed receive size for the next message.
By sending a second message with a large value (>1420 bytes)
the attacker can then achieve a heap buffer overflow.
This fix replaces min_t(int, ...) with min_t(u32) |
| In the Linux kernel, the following vulnerability has been resolved:
ceph: do not propagate page array emplacement errors as batch errors
When fscrypt is enabled, move_dirty_folio_in_page_array() may fail
because it needs to allocate bounce buffers to store the encrypted
versions of each folio. Each folio beyond the first allocates its bounce
buffer with GFP_NOWAIT. Failures are common (and expected) under this
allocation mode; they should flush (not abort) the batch.
However, ceph_process_folio_batch() uses the same `rc` variable for its
own return code and for capturing the return codes of its routine calls;
failing to reset `rc` back to 0 results in the error being propagated
out to the main writeback loop, which cannot actually tolerate any
errors here: once `ceph_wbc.pages` is allocated, it must be passed to
ceph_submit_write() to be freed. If it survives until the next iteration
(e.g. due to the goto being followed), ceph_allocate_page_array()'s
BUG_ON() will oops the worker.
Note that this failure mode is currently masked due to another bug
(addressed next in this series) that prevents multiple encrypted folios
from being selected for the same write.
For now, just reset `rc` when redirtying the folio to prevent errors in
move_dirty_folio_in_page_array() from propagating. Note that
move_dirty_folio_in_page_array() is careful never to return errors on
the first folio, so there is no need to check for that. After this
change, ceph_process_folio_batch() no longer returns errors; its only
remaining failure indicator is `locked_pages == 0`, which the caller
already handles correctly. |
| Jenkins Matrix Authorization Strategy Plugin 2.0-beta-1 through 3.2.9 (both inclusive) invokes parameterless constructors of classes specified in configuration when deserializing inheritance strategies, without restricting the classes that can be instantiated, allowing attackers with Item/Configure permission to instantiate arbitrary types, which may lead to information disclosure or other impacts depending on the classes available on the classpath. |
| A missing permission check in Jenkins GitHub Branch Source Plugin 1967.vdea_d580c1a_b_a_ and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL with attacker-specified GitHub App credentials. |
| An authorization bypass (CWE-639) in the GetUserRoles gRPC API endpoint in Velocidex Velociraptor below version 0.76.5 allows any authenticated low-privilege user to retrieve the complete ACL policy (roles and permissions) for any user across all organizations by supplying targeted Name and Org parameters via a network request. |
| Text::CSV_XS versions before 1.62 for Perl have a use-after-free when registered callbacks extend the Perl argument stack, which may enable type confusion or memory corruption.
The Parse, print, getline, and getline_all methods invoke registered callbacks (for example after_parse, before_print, or on_error) and cache the Perl argument stack pointer across the call. If a callback extends the argument stack enough to trigger a reallocation, the return value is written through the stale pointer into the freed buffer, and the caller reads the original $self argument as the return value instead.
Calling code that expects parsed data from getline_all receives the Text::CSV_XS object in its place, leading to logic errors or crashes. Text::CSV_XS objects used without any registered callbacks are not affected. |
| Redis is an in-memory data structure store. In versions of redis-server up to 8.6.3, the RESTORE command does not properly validate serialized values. An authenticated attacker with permission to execute RESTORE can supply a crafted serialized payload that triggers invalid memory access and may lead to remote code execution. A workaround is to restrict access to the RESTORE command with ACL rules. This is patched in version 8.6.3. |
| Uncontrolled Search Path Element vulnerability in WatchGuard Agent on Windows allows Using Malicious Files.This issue affects WatchGuard Agent before 1.25.03.0000. |
| Use of Hard-coded Cryptographic Key vulnerability in WatchGuard Agent on Windows allows Inclusion of Code in Existing Process.This issue affects WatchGuard Agent: before 1.25.03.0000. |
| Incorrect permission assignment for a resource in the patch management component of the WatchGuard Agent on Windows allows an authenticated local user to elevate their privileges to NT AUTHORITY\\SYSTEM. |
| Stack-based Buffer Overflow vulnerability in the WatchGuard Agent discovery service on Windows allows Overflow Buffers. An unauthenticated attacker on the same local network could exploit this vulnerability to crash the agent service. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: fix potential race in tcp_v6_syn_recv_sock()
Code in tcp_v6_syn_recv_sock() after the call to tcp_v4_syn_recv_sock()
is done too late.
After tcp_v4_syn_recv_sock(), the child socket is already visible
from TCP ehash table and other cpus might use it.
Since newinet->pinet6 is still pointing to the listener ipv6_pinfo
bad things can happen as syzbot found.
Move the problematic code in tcp_v6_mapped_child_init()
and call this new helper from tcp_v4_syn_recv_sock() before
the ehash insertion.
This allows the removal of one tcp_sync_mss(), since
tcp_v4_syn_recv_sock() will call it with the correct
context. |
| In the Linux kernel, the following vulnerability has been resolved:
minix: Add required sanity checking to minix_check_superblock()
The fs/minix implementation of the minix filesystem does not currently
support any other value for s_log_zone_size than 0. This is also the
only value supported in util-linux; see mkfs.minix.c line 511. In
addition, this patch adds some sanity checking for the other minix
superblock fields, and moves the minix_blocks_needed() checks for the
zmap and imap also to minix_check_super_block().
This also closes a related syzbot bug report. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing: ring-buffer: Fix to check event length before using
Check the event length before adding it for accessing next index in
rb_read_data_buffer(). Since this function is used for validating
possibly broken ring buffers, the length of the event could be broken.
In that case, the new event (e + len) can point a wrong address.
To avoid invalid memory access at boot, check whether the length of
each event is in the possible range before using it. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Add SRCU protection for reading PDPTRs in __get_sregs2()
Add SRCU read-side protection when reading PDPTR registers in
__get_sregs2().
Reading PDPTRs may trigger access to guest memory:
kvm_pdptr_read() -> svm_cache_reg() -> load_pdptrs() ->
kvm_vcpu_read_guest_page() -> kvm_vcpu_gfn_to_memslot()
kvm_vcpu_gfn_to_memslot() dereferences memslots via __kvm_memslots(),
which uses srcu_dereference_check() and requires either kvm->srcu or
kvm->slots_lock to be held. Currently only vcpu->mutex is held,
triggering lockdep warning:

| In the Linux kernel, the following vulnerability has been resolved:
net: Drop the lock in skb_may_tx_timestamp()
skb_may_tx_timestamp() may acquire sock::sk_callback_lock. The lock must
not be taken in IRQ context, only softirq is okay. A few drivers receive
the timestamp via a dedicated interrupt and complete the TX timestamp
from that handler. This will lead to a deadlock if the lock is already
write-locked on the same CPU.
Taking the lock can be avoided. The socket (pointed by the skb) will
remain valid until the skb is released. The ->sk_socket and ->file
member will be set to NULL once the user closes the socket which may
happen before the timestamp arrives.
If we happen to observe the pointer while the socket is closing but
before the pointer is set to NULL then we may use it because both
pointer (and the file's cred member) are RCU freed.
Drop the lock. Use READ_ONCE() to obtain the individual pointer. Add a
matching WRITE_ONCE() where the pointer are cleared. |
| In the Linux kernel, the following vulnerability has been resolved:
media: i2c/tw9903: Fix potential memory leak in tw9903_probe()
In one of the error paths in tw9903_probe(), the memory allocated in
v4l2_ctrl_handler_init() and v4l2_ctrl_new_std() is not freed. Fix that
by calling v4l2_ctrl_handler_free() on the handler in that error path. |
