CVE-2026-90085
In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: fix NULL deref in NIX TM tree debugfs read path rvu_dbg_nix_tm_tree_display() dereferences pfvf->sq_ctx without checking whether the SQ context has been allocated. Reading /sys/kernel/debug/octeontx2/nix/tm_tree for a NIX LF whose transmit queues are not set up triggers a kernel oops. Guard the read path the same way rvu_dbg_nix_tm_tree_write() already does and return -EINVAL with a seq_file message when sq_ctx is NULL.
