In the Linux kernel, the following vulnerability has been resolved: mt76: mt7921: fix kernel panic by accessing unallocated eeprom.data The MT7921 driver no longer uses eeprom.data, but the relevant code has not been removed completely since commit 16d98b548365 "mt76: mt7921: rely on...

kernel: gfs2: NULL pointer dereference in gfs2_evict_inode()

A NULL pointer dereference flaw was found in the gfs2 file system in the Linux kernel. This issue occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. This flaw allows a privileged local user to cause ...

kernel: scsi: storvsc: Fix handling of virtual Fibre Channel timeouts

In the Linux kernel, the following vulnerability has been resolved: scsi: storvsc: Fix handling of virtual Fibre Channel timeouts Hyper-V provides the ability to connect Fibre Channel LUNs to the host system and present them in a guest VM as a SCSI device. I/O to the vFC device is handled by the...

kernel: ptdma: pt_core_execute_cmd() should use spinlock

In the Linux kernel, the following vulnerability has been resolved: ptdma: ptcoreexecutecmd should use spinlock The interrupt handler ptcoreirqhandler of the ptdma driver can be called from interrupt context. The code flow in this function can lead down to ptcoreexecutecmd which will attempt to...

kernel: ipv6: ensure sane device mtu in tunnels

A flaw was found in the Linux kernel’s IPv6 networking code affecting the handling of IPv6 GRE tunnels. Under certain conditions, an IPv6 tunnel configuration could result in an invalid MTU Maximum Transmission Unit value being written to a network device without sanitization. Because the MTU val...

kernel: dmaengine: qcom-adm: fix wrong sizeof config in slave_config

A logic error was found in the Linux kernel Qualcomm ADM DMA engine driver's slave configuration handling. A local user with privileges to configure DMA operations can trigger DMA slave setup on Qualcomm ADM hardware, causing the driver to use an incorrect size comparison pointer size instead of...

kernel: HID: intel-ish-hid: Fix kernel panic during warm reset

In the Linux kernel, the following vulnerability has been resolved: HID: intel-ish-hid: Fix kernel panic during warm reset During warm reset device-fwclient is set to NULL. If a bus driver is registered after this NULL setting and before new firmware clients are enumerated by ISHTP, kernel panic...
