Very low probability of exploitation
EPSS predicts the probability of exploitation in the next 30 days based on real-world threat data, complementing CVSS severity scores with actual risk assessment.
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix kernel BUG in ocfs2_find_victim_chain
syzbot reported a kernel BUG in ocfs2_find_victim_chain() because the
cl_next_free_rec field of the allocation chain list (next free slot in
the chain list) is 0, triggring the BUG_ON(!cl->cl_next_free_rec)
condition in ocfs2_find_victim_chain() and panicking the kernel.
To fix this, an if condition is introduced in ocfs2_claim_suballoc_bits(), just before calling ocfs2_find_victim_chain(), the code block in it being executed when either of the following conditions is true:
cl_next_free_rec is equal to 0, indicating that there are no free
chains in the allocation chain listcl_next_free_rec is greater than cl_count (the total number of
chains in the allocation chain list)Either of them being true is indicative of the fact that there are no chains left for usage.
This is addressed using ocfs2_error(), which prints the error log for debugging purposes, rather than panicking the kernel.
