CVE-2026-54905

concurrent-ruby is a modern concurrency tools for Ruby. Prior to 1.3.7, Concurrent::ReentrantReadWriteLock can incorrectly grant a write lock after one thread acquires the read lock 32,768 times. The lock stores a thread's local read and write hold counts in one integer. The low 15 bits are used...

CVE-2026-54906

concurrent-ruby is a modern concurrency tools for Ruby. Prior to 1.3.7, Concurrent::ReadWriteLockreleasewritelock does not verify that the calling thread acquired the write lock. Any thread with access to the lock object can release an active write lock held by another thread. A second writer can...

CVE-2026-53088

In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: fix off-by-one in bcmgenetputtxcb The writeptr points to the next open txcb. We want to return the txcb that gets rewinded, so we must rewind the pointer first then return the txcb that it points to. That way the...

CVE-2026-53063

In the Linux kernel, the following vulnerability has been resolved: dm cache: fix write hang in passthrough mode The invalidateremove function has incomplete logic for handling write hit bios after cache invalidation. It sets up the remapping for the overwritebio but then drops it immediately...

CVE-2026-53017

In the Linux kernel, the following vulnerability has been resolved: f2fs: fix data loss caused by incorrect use of natentry flag Data loss can occur when fsync is performed on a newly created file before any checkpoint has been written concurrently with a checkpoint operation. The scenario is as...

CVE-2026-53105

CVE-2026-53105 is a Linux kernel vulnerability in the wifi mt76 mt7925 driver. It fixes a NULL pointer dereference by explicitly checking the vif for NULL before calling ieee80211_vif_is_mld(vif), preventing potential kernel panic when vif is uninitialized. Upstream references show the fix in sta...
