kernel: drm/xe: Fix error cleanup in xe_exec_queue_create_ioctl()

A flaw was found in the Linux kernel. Specifically, within the drm/xe graphics driver, two error handling issues in the xeexecqueuecreateioctl function could lead to memory corruption. This could result in a dangling pointer or a use-after-free vulnerability. A local attacker could potentially...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: Wifi: rtw88: Fixed an alignment fault in rtwcoreenablebeacon. The rtwcoreenablebeacon function reads 4 bytes from an address that is not a multiple of 4. This results in a crash on some systems. Instead, only 1 byte is...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: can: gsusb: gsusbxmitcallback: fixed the handling of failed transmitted URBs. The driver lacks the necessary cleanup steps after failed transfers of URBs. This results in one fewer available URB per error. This leads to reduced...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: hns3 – added validation of the VLAN ID before using it. Currently, the VLAN ID can be used without validation when receiving a VLAN configuration mailbox from VF. The length of vlansdelfailbmap is BITSTOLONGSVLANNVID. This m...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: clocksource/drivers/shtmu: Always leave the device running after a probe. The TMU device can be used both as a clocksource and as a clockevent provider. The driver attempts to manage its own power state and clock settings—turning...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: Fixed the issue where the PF driver crashed during kexec kernel booting. During a kexec reboot, the hardware is not power-cycle, so the AF state from the old kernel can persist into the new kernel. When the AF and P...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/xe/oa: Limit numsyncs to prevent oversized allocations. The OA open parameters did not validate numsyncs, allowing userspace to pass arbitrarily large values, potentially leading to excessive allocations. A check was added to...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fixed the issue where UMR hangs in the LAG error state during device unloading. During a firmware reset in LAG mode, a race condition causes the driver to hang indefinitely while waiting for UMR completion during devic...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: dmaengine: fsl-edma: Do not explicitly disable clocks in .remove The clocks in fsledmaengine::muxclk are allocated and enabled using devmclkgetenabled, which automatically cleans up these resources. However, these clocks are...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: leds: led-class: Only add the LED to ledslist when it is fully ready. Before this change, the LED was added to ledslist before the ledinitcore function was called—that is, before ledclassdev.setbrightnesswork was initialized. Thi...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: macb: The call order for unregisternetdev in macbremove has been corrected. When removing a macb device, the driver calls phyexit before unregisternetdev. This results in a warning from kernfs: ------------ Cut here...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: usb: ChipIdea UDC: Fix for DMA and SG cleanup in epnuke The ChipIdea UDC driver may encounter errors where “not-page-aligned sg buffers” occur when a USB device is reconnected after being disconnected during an active transfer...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: clk: rs9: Reserve 8 struct clkhw slots for 9FGV0841. The 9FGV0841 has 8 outputs and registers 8 struct clkhw structures. Ensure that there are 8 slots available for these newly registered clkhw pointers. Otherwise, out-of-bounds...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: Fixed a missing pointer check in the hdacomponentmanagerinit function. The componentmatchadd function may assign the ‘matchptr’ pointer the value ERRPTR-ENOMEM, which will subsequently be dereferenced. The call stack...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Wifi: RSI: Do not default to -EOPNOTSUPP in rsimac80211config. This triggers a WARNON in ieee80211hwconfinit, and this is not the expected behavior from the driver. Other drivers also default to 0...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: In net: liquidio, there is an issue where the netdev pointer must be initialized before queue setup is performed. In setupnicdevices, the netdev is allocated using allocetherdevmq. However, the pointer to this structure is stored...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: In the chips-media: wave5 module, the order of device cleanup was corrected to prevent kernel panic. The process of removing video devices was moved to the beginning of the removal function to ensure that all video operations are...
