Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 7.1-rc3
Description
A double free issue exists in the
qed cxt tables alloc() function. When a PF or VF CID bitmap allocation fails, qed cid map alloc() triggers a jump to cid map fail and frees previously allocated CID bitmaps. Subsequently, qed cxt tables alloc() calls qed cxt mngr free(), which invokes qed cid map free() a second time on the same memory.Recommendations
Update the Linux kernel to version 7.1-rc3 or later.
