cpufreq: qcom: fix writes in read-only memory region
This commit fixes a kernel oops because of a write in some read-only memory:
[ 9.068287] Unable to handle kernel write to read-only memory at virtual address ffff800009240ad8
..snip..
[ 9.138790] Internal error: Oops: 9600004f [#1] PREEMPT SMP
..snip..
[ 9.269161] Call trace:
[ 9.276271] __memcpy+0x5c/0x230
[ 9.278531] snprintf+0x58/0x80
[ 9.282002] qcom_cpufreq_msm8939_name_version+0xb4/0x190
[ 9.284869] qcom_cpufreq_probe+0xc8/0x39c
..snip..
The following line defines a pointer that point to a char buffer stored
in read-only memory:
char *pvs_name = "speedXX-pvsXX-vXX";
This pointer is meant to hold a template "speedXX-pvsXX-vXX" where the
XX values get overridden by the qcom_cpufreq_krait_name_version function. Since
the template is actually stored in read-only memory, when the function
executes the following call we get an oops:
snprintf(*pvs_name, sizeof("speedXX-pvsXX-vXX"), "speed%d-pvs%d-v%d",
speed, pvs, pvs_ver);
To fix this issue, we instead store the template name onto the stack by
using the following syntax:
char pvs_name_buffer[] = "speedXX-pvsXX-vXX";
Because the `pvs_name` needs to be able to be assigned to NULL, the
template buffer is stored in the pvs_name_buffer and not under the
pvs_name variable. |
| A stack buffer overflow vulnerability exists in the ToToLink LR1200GB (V9.1.0u.6619_B20230130) and NR1800X (V9.1.0u.6681_B20230703) Router firmware within the cstecgi.cgi binary (sub_42F32C function). The web interface reads the "lang" parameter and constructs Help URL strings using sprintf() into fixed-size stack buffers without proper length validation. Maliciously crafted input can overflow these buffers, potentially leading to arbitrary code execution or memory corruption, without requiring authentication. |
| Inappropriate implementation in Passkeys in Google Chrome prior to 140.0.7339.80 allowed a local attacker to obtain potentially sensitive information via debug logs. (Chromium security severity: Low) |
| tpm2-tss is an open source software implementation of the Trusted Computing Group (TCG) Trusted Platform Module (TPM) 2 Software Stack (TSS2). In versions prior to 4.1.0-rc0, 4.0.1, and 3.2.2-rc1, `Tss2_RC_SetHandler` and `Tss2_RC_Decode` both index into `layer_handler` with an 8 bit layer number, but the array only has `TPM2_ERROR_TSS2_RC_LAYER_COUNT` entries, so trying to add a handler for higher-numbered layers or decode a response code with such a layer number reads/writes past the end of the buffer. This Buffer overrun, could result in arbitrary code execution. An example attack would be a MiTM bus attack that returns 0xFFFFFFFF for the RC. Given the common use case of TPM modules an attacker must have local access to the target machine with local system privileges which allows access to the TPM system. Usually TPM access requires administrative privilege. Versions 4.1.0-rc0, 4.0.1, and 3.2.2-rc1 fix the issue. |

| A vulnerability was found in PostgreSQL with the use of the MERGE command, which fails to test new rows against row security policies defined for UPDATE and SELECT. If UPDATE and SELECT policies forbid some rows that INSERT policies do not forbid, a user could store such rows. |
| A flaw was found in ghostscript. The fix for CVE-2020-16305 in ghostscript was not included in RHSA-2021:1852-06 advisory as it was claimed to be. This issue only affects the ghostscript package as shipped with Red Hat Enterprise Linux 8. |
| In mutt and neomutt, PGP encryption does not use the --hidden-recipient mode which may leak the Bcc email header field by inferring from the recipients info. |
| An out-of-bounds read vulnerability was found in OpenSC packages within the MyEID driver when handling symmetric key encryption. Exploiting this flaw requires an attacker to have physical access to the computer and a specially crafted USB device or smart card. This flaw allows the attacker to manipulate APDU responses and potentially gain unauthorized access to sensitive data, compromising the system's security. |
| An out-of-bounds read flaw was found in w3m, in the Strnew_size function in Str.c. This issue may allow an attacker to cause a denial of service through a crafted HTML file. |
| A flaw was found in the keylime attestation verifier, which fails to flag a device's submitted TPM quote as faulty when the quote's signature does not validate for some reason. Instead, it will only emit an error in the log without flagging the device as untrusted. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mdiobus: Fix potential out-of-bounds clause 45 read/write access
When using publicly available tools like 'mdio-tools' to read/write data
from/to network interface and its PHY via C45 (clause 45) mdiobus,
there is no verification of parameters passed to the ioctl and
it accepts any mdio address.
Currently there is support for 32 addresses in kernel via PHY_MAX_ADDR define,
but it is possible to pass higher value than that via ioctl.
While read/write operation should generally fail in this case,
mdiobus provides stats array, where wrong address may allow out-of-bounds
read/write.
Fix that by adding address verification before C45 read/write operation.
While this excludes this access from any statistics, it improves security of
read/write operation. |
| In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix oops in write-retry from mis-resetting the subreq iterator
Fix the resetting of the subrequest iterator in netfs_retry_write_stream()
to use the iterator-reset function as the iterator may have been shortened
by a previous retry. In such a case, the amount of data to be written by
the subrequest is not "subreq->len" but "subreq->len -
subreq->transferred".
