USN-8604-1: Linux kernel (Azure) vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - Foo-over-UDP FOU; - ARM64 architecture; - x86 architecture; - Block layer subsystem; - Cryptographic API; - Drivers...

PT-2026-64356

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The rockchip GPIO driver contains several teardown issues and resource leaks within its remove path and error handling. Specifically, the debounce clock bank-db clk is obtained via of cl...

PT-2026-64353

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A deadlock can occur during the removal of a shared GPIO proxy's parent. This issue stems from an excessively wide critical section using a mutex embedded in the gpio shared entry...

CVE-2026-64023

A flaw was found in the Linux kernel's GPIO General Purpose Input/Output aggregator module. This vulnerability occurs when an error condition causes memory to be prematurely freed while still being referenced in a lookup table. A local attacker could potentially exploit this timing issue, leading...

CVE-2026-64022

A flaw was found in the Linux kernel's GPIO General Purpose Input/Output aggregator component. When the aggregator device is deactivated after being configured using configfs, a dynamic software node is not properly removed. This oversight leads to a resource leak, which could potentially be...

SUSE CVE-2026-63949

In the Linux kernel, the following vulnerability has been resolved: auxdisplay: line-display: fix OOB read on zero-length messagestore linedispdisplay unconditionally reads msgcount - 1 before checking whether count is zero, so a write of zero bytes to the message sysfs attribute hits msg-1:...

SUSE CVE-2026-64022

In the Linux kernel, the following vulnerability has been resolved: gpio: aggregator: remove the software node when deactivating the aggregator The dynamic software node we create for the aggregator platform device when using configfs is leaked when the device is deactivated. Destroy it as the la...

SUSE CVE-2026-64023

In the Linux kernel, the following vulnerability has been resolved: gpio: aggregator: fix a potential use-after-free On error we free aggr-lookups-devid before removing the entry from the lookup table. If a concurrent thread calls gpiodfind before we remove the entry, it could iterate over the li...

SUSE CVE-2026-64083

In the Linux kernel, the following vulnerability has been resolved: hwmon: pmbus/adm1266 reject short block-read responses in the GPIO accessors adm1266gpioget and adm1266gpiogetmultiple both compose the pin-status word as pinsstatus = readbuf0 + readbuf1 8; right after i2csmbusreadblockdata,...

SUSE CVE-2026-64097

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Validate GPIO pin LUT table size before iterating Why&How The GPIO pin table parsers in getgpioi2cinfo and biosparsergetgpiopininfo derive an element count from the VBIOS tableheader.structuresize field, then...

CVE-2026-63949

A flaw was found in the Linux kernel's auxdisplay line-display subsystem. A local user can trigger an out-of-bounds read by writing a zero-length message to the message sysfs attribute. This occurs because the linedispdisplay function attempts to read a character from a zero-length buffer, leadin...

CVE-2026-64097

A flaw was found in the Linux kernel's AMD display drm/amd/display component. This vulnerability is caused by improper validation of the GPIO General Purpose Input/Output pin table size. An attacker could exploit this by providing a malformed Video BIOS VBIOS that leads to reading data beyond its...

The vulnerability in the `lineinfo_changed_notify()` function of the `drivers/gpio/gpiolib-cdev.c` driver for the Linux kernel’s GPIO driver allows an attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the lineinfochangednotify function in the drivers/gpio/gpiolib-cdev.c driver for the Linux kernel’s GPIO driver is related to errors during link counter updates. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...
