CVE-2026-64091 batman-adv: tt: fix TOCTOU race for reported vlans

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: fix TOCTOU race for reported vlans The local TT based TVLV is generated by first checking the number of VLANs which have at least one TT entry. A new buffer with the correct size for the VLANs is then allocated...

CVE-2026-64091

CVE-2026-64091 affects batman-adv in the Linux kernel, addressing a TOCTOU race in the TT-based TVLV generation for reported VLANs. The issue arises because the buffer used to hold VLAN entries is sized based on a prefilter that may undercount or overcount VLANs during parallel updates, while the...

SUSE CVE-2026-41678

rust-openssl provides OpenSSL bindings for the Rust programming language. From to before 0.10.78, aes::unwrapkey contains an incorrect assertion: it checks that out.len + 8 = in.len - 8, ensuring the output buffer is large enough. Because of the inverted check, the function only accepts buffers a...
