CVE-2026-64508

CVE-2026-64508 relates to a Linux kernel vulnerability in BPF JIT memory reuse. The issue arises when the BPF JIT allocator reuses space for new programs, potentially letting indirect jumps reuse stale branch predictions. Fix implemented: flush indirect branch predictors on JIT memory reuse via a...

PYSEC-2026-3010 pypdf: Inefficient decoding of FlateDecode PNG predictor streams

Impact An attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires accessing a stream which uses the /FlateDecode filter with a PNG predictor. Patches This has been fixed in pypdf==6.12.2. Workarounds If you cannot upgrade yet, consider applying the changes...

PYSEC-2026-3011 pypdf: Manipulated FlateDecode predictor parameters can exhaust RAM

Impact An attacker who uses this vulnerability can craft a PDF which leads to the RAM being exhausted. This requires accessing a stream compressed using /FlateDecode with a /Predictor unequal 1 and large predictor parameters. Patches This has been fixed in pypdf==6.10.2. Workarounds If you cannot...
