Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: Tracing: kprobe: Fixed a memory leak in testgenkprobe/kretprobecmd. testgenkprobecmd only frees the buffer in the “fail path”; therefore, the buffer may leak when there is no failure. Move the kfreebuf call from the “fail path...

SUSE CVE-2026-89749

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix crash passing ERRPTR to kthreadstop eventteststuff calls kthreadrun and unconditionally passes the returned taskstruct pointer to kthreadstop. kthreadrun returns an error pointer such as ERRPTR-ENOMEM when kthread...

CVE-2026-89749

A flaw was found in the Linux kernel. Specifically, within the tracing subsystem, the eventteststuff function can pass an invalid error pointer to kthreadstop if kthreadrun fails to create a kernel thread. This improper handling of error pointers, particularly under memory pressure, leads to...

CVE-2026-89747

A flaw was found in the Linux kernel's tracing component. A local attacker could exploit a use-after-free vulnerability, a type of memory corruption, by manipulating the tracepipe functionality. This occurs when the system attempts to read from memory that has already been released, leading to...

CVE-2026-89748

A flaw was found in the Linux kernel's tracing subsystem. An issue in the simpleringbufferswapreaderpage function, related to retry exhaustion during ring buffer reader page swaps, can lead to incorrect handling of successful or failed operations. This can result in corruption of the ring buffer,...

CVE-2026-89746

A flaw was found in the Linux kernel's tracing component. A local user can exploit a use-after-free vulnerability by registering multiple histogram triggers with the same name. This action causes the kernel to attempt to access freed memory, leading to a system crash and a Denial of Service DoS...
