In the Linux kernel, the following vulnerability has been resolved: hid: cp2112: Fix duplicate workqueue initialization Previously the cp2112 driver called INITDELAYEDWORK within cp2112gpioirqstartup, resulting in duplicate initilizations of the workqueue on subsequent IRQ startups following an...

kernel: scsi: qla2xxx: Use raw_smp_processor_id() instead of smp_processor_id()

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Use rawsmpprocessorid instead of smpprocessorid The following call trace was observed: localhost kernel: nvme nvme0: NVME-FC0: controller connect complete localhost kernel: BUG: using smpprocessorid in preemptible...

kernel: md/raid5-cache: fix a deadlock in r5l_exit_log()

A deadlock vulnerability was found in the md RAID5 cache r5l subsystem in the Linux kernel. In r5lexitlog, flushwork is called while holding reconfigmutex, which waits for disablewritebackwork to complete. However, r5cdisablewritebackasync calls waitevent which requires conf-log to be NULL, but...

kernel: mptcp: fix UaF in listener shutdown

A flaw was found in the Linux kernel's Multipath TCP MPTCP subsystem. An improper cleanup sequence during listener socket shutdown can lead to a use-after-free condition where the kernel accesses socket memory after it has already been released. A local attacker could exploit this vulnerability t...

kernel: scsi: qedi: Fix use after free bug in qedi_remove()

A use-after-free vulnerability was found in the Linux kernel's QLogic qedi iSCSI driver. When the driver is removed via qediremove, the SCSI host structure may be freed while recoverywork or boarddisablework are still running. The work handlers then access the freed qedi-shost structure, causing ...

kernel: cxgb4: use-after-free in ch_flower_stats_cb()

A use-after-free vulnerability was found in the cxgb4 driver in the Linux kernel. The bug occurs when the cxgb4 device is detaching due to a possible rearming of the flowerstatstimer from the work queue. This flaw allows a local user to crash the system, causing a denial of service condition...
