CVE-2026-97443

A flaw was found in the Linux kernel's perf subsystem. During error handling for failed performance event allocation, the kernel unconditionally attempts to unregister a function tracer that was never successfully enabled. A local user can exploit this flaw to trigger a kernel warning, which may...

CVE-2026-93817

A flaw was found in the Linux kernel's performance events perf subsystem. This vulnerability occurs because memory allocated for event address filters is released prematurely while still in active use by other kernel processes. A local user could exploit this use-after-free flaw during performanc...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: ARM: 9064/1: hwbreakpoint: Do not directly check the event’s overflowhandler hook The commit 1879445dfa7b “perf/core: Set event’s default ::overflowhandler” sets a default event-overflowhandler in perfeventalloc, and replaces the...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the Linux kernel. A memory use-after-free vulnerability was identified in the perf subsystem, allowing a local attacker with permission to monitor perf events, thereby corrupting memory and potentially escalating privileges. The most significant threat of this vulnerabili...

SUSE CVE-2026-72325

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd/core: Avoid enabling BRS from the SVM reload path Branch Sampling BRS and Last Branch Record LBR are mutually exclusive hardware features, and users of both are tracked via cpuc-lbrusers. When SVM is toggled on a CPU...

CVE-2026-80602

A flaw was found in the Linux kernel's perf subsystem. This vulnerability allows a local user to gain access to sensitive kernel memory addresses. This occurs because the system's branch stack, intended for user-only information, can inadvertently include kernel addresses, leading to an informati...

CVE-2026-80602

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd/lbr: Fix kernel address leakage A user-only branch stack can contain branches that originate from the kernel. As a result, kernel addresses are exposed to user space even when PERFSAMPLEBRANCHUSER is requested. On AM...

CVE-2026-80602

CVE-2026-80602 is an information disclosure vulnerability in the Linux kernel 's perf/x86/amd/lbr subsystem. On AMD processors supporting X86_FEATURE_AMD_LBR_V2 , the hardware branch filter only validates the privilege level of the branch target , not the branch from address. As a result, SYSRET/...

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-098933 advisory. In the Linux kernel, the following vulnerability has been resolved: perf: Fix perfeventoverflow vs perfremovefromcontext race Make sure that perfeventoverflow runs...

CVE-2026-74637

A flaw was found in the Linux kernel's perf subsystem. A local attacker could exploit a use-after-free vulnerability when a perf event group's sibling is detached but remains active, and its pointer to the group leader is not properly updated. This improper handling can lead to a system crash,...

CVE-2026-72237

A flaw was found in the Linux kernel. A local user can exploit a vulnerability in the perf subsystem on AMD processors utilizing the Branch Sampling BRS feature. This flaw occurs because the software filtering mechanism for branch records only validates the branch-to address, leaving the...
