Detailsinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel up to 5.10.176/5.15.104/6.1.21/6.2.8. This issue affects an unknown functionality. The manipulation of the argument perf_output_begin with an unknown input leads to a out-of-bounds vulnerability. Using CWE to declare the problem leads to CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: perf/core: Fix perf_output_begin parameter is incorrectly invoked in perf_event_bpf_output syzkaller reportes a KASAN issue with stack-out-of-bounds.

However, perf_event_bpf_output uses incorrect parameter to convert small-sized data (struct perf_bpf_event) into large-sized data (struct perf_sample_data), which causes memory overwriting occurs in __perf_event_header__init_id.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2023-53065 since 05/02/2025. The exploitation is known to be difficult. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 279319 (EulerOS Virtualization 2.13.0 : kernel (EulerOS-SA-2025-2581)), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 5.10.177, 5.15.105, 6.1.22 or 6.2.9 eliminates this vulnerability. Applying the patch ddcf8320003638a06eb1e46412e045d0c5701575/ac5f88642cb211152041f84a985309e9af4baf59/ff8137727a2af4ad5f6e6c8b9f7ec5e8db9da86c/3a776fddb4e5598c8bfcd4ad094fba34f9856fc9/eb81a2ed4f52be831c9fb879752d89645a312c13 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.
