In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Set SDEV_OFFLINE when UFS is shut down There is a history of deadlock if reboot is performed at the beginning of booting. SDEV_QUIESCE was set for all LU's scsi_devices by UFS shutdown, and at that time the audio driver was waiting on blk_mq_submit_bio() holding a mutex_lock while reading the fw binary. After that, a deadlock issue occurred while audio driver shutdown was waiting for mutex_unlock of blk_mq_submit_bio(). To solve this, set SDEV_OFFLINE for all LUs except WLUN, so that any I/O that comes down after a UFS shutdown will return an error.

In the Linux kernel, the following vulnerability has been resolved: nouveau/dmem: Fix vulnerability in migrate_to_ram upon copy error The `nouveau_dmem_copy_one` function ensures that the copy push command is sent to the device firmware but does not track whether it was executed successfully. In the case of a copy error (e.g., firmware or hardware failure), the copy push command will be sent via the firmware channel, and `nouveau_dmem_copy_one` will likely report success, leading to the `migrate_to_ram` function returning a dirty HIGH_USER page to the user. This can result in a security vulnerability, as a HIGH_USER page that may contain sensitive or corrupted data could be returned to the user. To prevent this vulnerability, we allocate a zero page. Thus, in case of an error, a non-dirty (zero) page will be returned to the user. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nouveau/dmem: Se corrige la vulnerabilidad en migrants_to_ram tras un error de copia. La función `nouveau_dmem_copy_one` garantiza que el comando de copia push se envíe al firmware del dispositivo, pero no rastrea si se ejecutó correctamente. En el caso de un error de copia (por ejemplo, fallo del firmware o hardware), el comando de copia push se enviará a través del canal de firmware y `nouveau_dmem_copy_one` probablemente informará el éxito, lo que llevará a la función `migrate_to_ram` a devolver una página HIGH_USER sucia al usuario. • https://git.kernel.org/stable/c/5be73b690875f7eb2d2defb54ccd7f2f12074984 https://git.kernel.org/stable/c/73f75d2b5aee5a735cf64b8ab4543d5c20dbbdd9 https://git.kernel.org/stable/c/8c3de9282dde21ce3c1bf1bde3166a4510547aa9 https://git.kernel.org/stable/c/614bfb2050982d23d53d0d51c4079dba0437c883 https://git.kernel.org/stable/c/697e3ddcf1f8b68bd531fc34eead27c000bdf3e1 https://git.kernel.org/stable/c/ab4d113b6718b076046018292f821d5aa4b844f8 https://git.kernel.org/stable/c/835745a377a4519decd1a36d6b926e369b3033e2 •

In the Linux kernel, the following vulnerability has been resolved: RDMA/mad: Improve handling of timed out WRs of mad agent Current timeout handler of mad agent acquires/releases mad_agent_priv lock for every timed out WRs. This causes heavy locking contention when higher no. of WRs are to be handled inside timeout handler. This leads to softlockup with below trace in some use cases where rdma-cm path is used to establish connection between peer nodes Trace: ----- BUG: soft lockup - CPU#4 stuck for 26s!

In the Linux kernel, the following vulnerability has been resolved: thermal: intel: int340x: processor: Fix warning during module unload The processor_thermal driver uses pcim_device_enable() to enable a PCI device, which means the device will be automatically disabled on driver detach. Thus there is no need to call pci_disable_device() again on it. With recent PCI device resource management improvements, e.g. commit f748a07a0b64 ("PCI: Remove legacy pcim_release()"), this problem is exposed and triggers the warining below.
