Aug 4 RESCORED — CVE-2024-36476 (Linux). CVSS 9.8 → 5.5 (NVD).
Description
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rtrs: Ensure 'ib_sge list' is accessible
Move the declaration of the 'ib_sge list' variable outside the
'always_invalidate' block to ensure it remains accessible for use
throughout the function.
Previously, 'ib_sge list' was declared within the 'always_invalidate'
block, limiting its accessibility, then caused a
'BUG: kernel NULL pointer dereference'[1].
