  "title": "linux: In the Linux kernel, the following vulnerability has been resolved:  jfs: fix uninitialized waitqueue in transaction...",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  jfs: fix uninitialized waitqueue in transaction manager  The transaction manager initialization in txInit() was not properly initializing TxBlock[0].waitor waitqueue, causing a crash when txEnd(0) is called on read-only filesystems.  When a filesystem is mounted read-only, txBegin() returns tid=0 to indicate no transaction. However, txEnd(0) still gets called and tries to access TxBlock[0].waitor via tid_to_tblock(0), but this waitqueue was never initialized because the initialization loop started at index 1 instead of 0.  This causes a \u0027non-static key\u0027 lockdep warning and system crash:   INFO: trying to register non-static key in txEnd  Fix by ensuring all transaction blocks including TxBlock[0] have their waitqueues properly initialized during txInit().",
