kernel: scsi: core: Remove the /proc/scsi/${proc_name} directory earlier

In the Linux kernel, the following vulnerability has been resolved: scsi: core: Remove the /proc/scsi/$procname directory earlier Remove the /proc/scsi/$procname directory earlier to fix a race condition between unloading and reloading kernel modules. This fixes a bug introduced in 2009 by commit...

CVE-2024-26846

In the Linux kernel, the following vulnerability has been resolved: nvme-fc: do not wait in vain when unloading module The module exit path has race between deleting all controllers and freeing 'left over IDs'. To prevent double free a synchronization between nvmedeletectrl and idadestroy has bee...

CVE-2024-26846

CVE-2024-26846 affects the Linux kernel’s nvme-fc unloading path. A race between nvme_delete_ctrl and ida_destroy could double-free IDs, causing module unload hangs. The fix adds synchronization to ensure nvme_delete_ctrl code runs before leaving nvme_fc_exit_module and flushes the nvme_delete_wq...

kernel: ALSA: ymfpci: Create card with device-managed snd_devm_card_new()

A flaw was found in the Linux kernel's ALSA ymfpci sound driver. During a previous refactoring commit that removed sndcardymfpciremove, the sndcardnew call was not updated to snddevmcardnew. This omission means sndcardfree is never called during module unload, leading to a kernel oops when...

kernel: net/mlx5e: Fix cleanup null-ptr deref on encap lock

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix cleanup null-ptr deref on encap lock During module is unloaded while a peer tc flow is still offloaded, first the peer uplink rep profile is changed to a nic profile, and so neigh encap lock is destroyed. Next duri...

kernel: Linux kernel: Memory leak in RDMA/irdma subsystem leads to Denial of Service

A flaw was found in the Linux kernel's RDMA/irdma subsystem. When the irdma module is unloaded, certain memory objects PBLEs are not properly released, leading to a memory leak. A local attacker could repeatedly trigger this condition, causing system memory to be exhausted and resulting in a Deni...
