USN-8123-1 mbedtls vulnerabilities

It was discovered that Mbed TLS incorrectly handled memory allocation failures. A remote attacker could possibly use this issue to crash the program. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. CVE-2021-44732 Jonathan Winzig discovered that Mbed TLS incorrectly handled crafted...

CVE-2026-23309

A flaw was found in the Linux kernel. When the 'triggerdataalloc' function fails to allocate memory and returns a null pointer, the subsequent 'triggerdatafree' function attempts to access this null pointer. This null pointer dereference can lead to a system crash, resulting in a Denial of Servic...

CVE-2026-23366

A flaw was found in the Linux kernel's Direct Rendering Manager DRM client component. This vulnerability occurs when the system attempts to destroy an uninitialized memory pointer, specifically the 'modes' variable within the drmclientmodesetprobe function, after a memory allocation failure. This...

EUVD-2026-15348

In the Linux kernel, the following vulnerability has been resolved: drm/client: Do not destroy NULL modes 'modes' in drmclientmodesetprobe may fail to kcalloc. If this occurs, we jump to 'out', calling modesdestroy on it, which dereferences it. This may result in a NULL pointer dereference in the...

CVE-2026-23360

In the Linux kernel, the following vulnerability has been resolved: nvme: fix admin queue leak on controller reset When nvmeallocadmintagset is called during a controller reset, a previous admin queue may still exist. Release it properly before allocating a new one to avoid orphaning the old queu...

CVE-2026-23309

In the Linux kernel, the following vulnerability has been resolved: tracing: Add NULL pointer check to triggerdatafree If triggerdataalloc fails and returns NULL, eventhisttriggerparse jumps to the outfree error path. While kfree safely handles a NULL pointer, triggerdatafree does not. This cause...

CVE-2026-23301

CVE-2026-23389

CVE-2026-23389 (Linux kernel ice component) : The issue is a memory leak in ice_set_ringparam() where tx_rings and xdp_rings are allocated before rx_rings. If rx_rings allocation fails, the code jumps to a done path that leaks both tx_rings and xdp_rings; if a per-Rx ring setup fails, code may ju...
