CVE-2026-46159

The CVE-2026-46159 issue affects the Linux kernel’s Btrfs code, specifically btrfs_ioctl_space_info(). A TOCTOU race occurs between two passes over block group RAID type lists: the first pass counts entries for allocation, the second fills the buffer and releases the groups_sem lock. If entries s...

CVE-2026-46139

CVE-2026-46139 covers the Linux kernel SMB client: when building an ACL descriptor in build_sec_desc(), a kzalloc-based allocation fix was introduced to zero-initialize the security descriptor buffer, replacing a previous kmalloc path. The change splits struct smb_acl's __le32 num_aces into __le1...
