CVE-2026-99129 in Linux
要約
〜によって MITRE • 2026年10月28日
In the Linux kernel, the following vulnerability has been resolved:
selinux: fix BPF token permission checks
Avoid multiple lookups of the bpffs creator SID using the token's file descriptor when the same information can be found via the resolved path/dentry (in selinux_bpf_token_create()) or the token itself (in selinux_bpf_map_create() and selinux_bpf_prog_load()). Not only does this simplify the code, it avoids potential TOCTOU issues if the user changes the token file descriptor passed into the kernel.
