CVE-2014-4611: Linux Kernel

Medium severity, CVSS 5.0. EPSS: 8.1% chance of exploitation in the next 30 days.

Integer overflow in the LZ4 algorithm implementation, as used in Yann Collet LZ4 before r118 and in the lz4_uncompress function in lib/lz4/lz4_decompress.c in the Linux kernel before 3.15.2, on 32-bit platforms might allow context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted Literal Run that would be improperly handled by programs not complying with an API limitation, a different vulnerability than CVE-2014-4715.

Affected products

• Linux Linux Kernel: before 3.15.2 (fixed in 3.15.2)
