Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: uprobes: Fixed a kernel information leak via “uprobes” vma. xoladdvma: Maps the uninitialized page allocated by createxolarea into user space. On some architectures x86, this memory is readable even without VMREAD or VMEXEC;...

SUSE CVE-2026-74584

In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxtre: zero shared page before exposing to userspace bnxtreallocucontext allocates uctx-shpg via getfreepageGFPKERNEL. The buddy allocator does not zero pages without GFPZERO, so the page contains stale kernel data from...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: VDUSE: Avoid leaking information to userspace. The bouncing of memory pages does not necessarily require page alignment; therefore, current VDUSE may still leak kernel information by mapping bounce pages to userspace. Allocate...

kernel: uprobes: fix kernel info leak via "[uprobes]" vma

A flaw was found in the Linux kernel's uprobes subsystem. When allocating memory for user space probes, the kernel maps an uninitialized memory page into a user space virtual memory area VMA. A local user can exploit this vulnerability to read uninitialized memory contents, resulting in an...

CVE-2024-53148

In the Linux kernel, the following vulnerability has been resolved: comedi: Flush partial mappings in error case If some remappfnrange calls succeeded before one failed, we still have buffer pages mapped into the userspace page tables when we drop the buffer reference with comedibufmapputbm. The...

Apple Mac OSX Kernel - Null Pointer Dereference in AppleMuxControl.kext

/ Source: https://bugs.chromium.org/p/project-zero/issues/detail?id=783 The method AppleGraphicsControlClient::checkArguments does actually appear to test whether the pointer at this+0xd8 is non-null, but uses it anyway : We can race external methods which call this with another thread calling...
