CVE-2026-93164

A flaw was found in the Linux kernel. Optimized uprobes, a mechanism for dynamic tracing, can improperly overwrite a protected memory region known as the redzone area. This occurs when a call instruction stores a return address on the stack without adequately adjusting the stack pointer,...

In the Linux kernel, the following vulnerabilities have been resolved: uprobes: Fixed a kernel information leak via “uprobes” virtual memory. The xoladdvma function maps the uninitialized page allocated by createxolarea into user space. On some architectures x86, this memory is readable even...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: perf: It is now required that CAPSYSADMIN be present for uprobes. Jann reports that uprobes can be used destructively when they are used in the middle of an instruction. The kernel only verifies that there is a valid instruction ...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed a UAF Use-after-Allocation issue by correcting mismatching between the bpfprog/attachment and tasks-trace-RCU flavors. Uprobes always use bpfprogrunarrayuprobe under tasks-trace-RCU protection. However, it is possible ...

CVE-2026-93164

CVE-2026-93164 affects the Linux kernel uprobes/x86 subsystem. The root cause is that optimized uprobes installed on a 5-byte NOP could clobber the x86 redzone area : the call instruction used to jump to the uprobe trampoline stores the return address on the stack, potentially overwriting tempora...

PT-2026-94960

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in optimized uprobes on x86 architecture where the call instruction used to store the return address on the stack can clobber the redzone area. The redzone is a region of...
