CVE-2022-48939: Linux Kernel

Low severity, CVSS 3.3. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: bpf: Add schedule points in batch ops syzbot reported various soft lockups caused by bpf batch operations. INFO: task kworker/1:1:27 blocked for more than 140 seconds. INFO: task hung in rcu_barrier Nothing prevents batch ops to process huge amount of data, we need to add schedule points in them. Note that maybe_wait_bpf_programs(map) calls from generic_map_delete_batch() can be factorized by moving the call after the loop. This will be done later in -next tree once we get this fix merged, unless there is strong opinion doing this optimization sooner.

Affected products

• Linux Linux Kernel: from 5.6, before 5.10.103 (fixed in 5.10.103); from 5.11, before 5.15.26 (fixed in 5.15.26); from 5.16, before 5.16.12 (fixed in 5.16.12)
