- Summary
- CVE-2025-68744 affecting package kernel for versions less than 6.6.121.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
bpf: Free special fields when update [lru_,]percpu_hash maps
As [lru_,]percpuhash maps support BPFKPTR_{REF,PERCPU}, missing calls to 'bpfobjfreefields()' in 'pcpucopyvalue()' could cause the memory referenced by BPFKPTR_{REF,PERCPU} fields to be held until the map gets freed.
Fix this by calling 'bpfobjfreefields()' after 'copymapvalue,_long' in 'pcpucopy_value()'.
