CVE-2026-45972 smb: client: fix potential UAF and double free in smb2_open_file()

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential UAF and double free in smb2openfile Zero out @erriov and @errbuftype before retrying SMB2open to prevent an UAF bug if @data != NULL, otherwise a double free...

CVE-2026-45876

CVE-2026-45876 affects the Linux kernel (arm64 architecture) in the arch_set_shadow_stack_status flow. The bug arises from error handling in alloc_gcs(), which can return an error-encoded pointer from do_mmap() instead of NULL. A NULL-based check fails to detect these errors, risking use of an in...

curl: Use-after-free in `curl_easy_duphandle()` with HTTP/2 stream-dependency tree

Hi all, We've found an issue in lib/easy.c where curleasyduphandle shallow-copies set.priority, so the original and the duplicate end up holding two independent pointer-typed variables that both reference the same heap-allocated Curldataprionode chain. Freeing the chain from one side leaves the...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Install a stub fence into potential unused fence pointers. When using cpu to update page tables, VM update fences are unused. Instead, install a stub fence into these fence pointers, rather than setting them to NULL...
