Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: nfs/blocklayout: Do not attempt unregistration for invalid block devices Since the commit d869da91cccb “nfs/blocklayout: Fix premature PR key unregistration”, unmounting a pNFS SCSI-layout-enabled NFS may cause a NULL blockdevice...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bnxten: Fixed a possible memory leak in bnxtrdmaauxdeviceinit. If ulp = kzalloc fails, the allocated edev will leak because it is not properly assigned, and the cleanup mechanism will not be able to free it. This issue was fixed ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ptp: vmclock: Set the driver data before it is used. If vmclockptpregister fails during probing, vmclockremove is called to clean up the ptp clock and miscellaneous devices. This function uses devgetdrvdata to access the vmclock...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: vduse: It is now checked that the offset is within the bounds when calling getconfig. This check only examines len, not offset. This could lead to an out-of-bounds read if offset dev-configsize. The issue arises because both...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: fbdev: Fixed the issue of unregistering framebuffers without a device. Framebuffers in OF do not have a underlying device in the Linux device hierarchy. Instead of hot-unplugging such non-existent devices, a regular unregister...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: thermal/debugfs: Prevent a use-after-free from occurring after the cdev removal. Since thermaldebugcdevremove does not run under cdev-lock, it can run in parallel with thermal Debugcdevstateupdate. This may free the struct therma...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: gpu: host1x – Fixed memory leak related to device names. The device names allocated by devsetname need to be freed before module unloading. However, this cannot be done because the reference count of the kobject, set during...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: cxl/ras: Fixed the device confusion related to the CPER handler. Upon inspection, the cxlcperhandleproterr function makes several fragile assumptions that can lead to crashes: 1. It assumes that the endpoints identified in the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: phylink: Added a lock to serialize concurrent writes to pl-phydev using phylinkresolve. Currently, phylinkresolve protects itself against concurrent calls to phylinkbringupPhyio or phylinkdisconnectPhyio that modify pl-phyde...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: vfio: Split migration operations from main device operations The vfio core checks whether the driver sets certain migration operations e.g., setstate/getstate, and accordingly calls those operations. However, currently, the ml...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: pmdomain: arm: Fixed NULL dereference upon removal of scmiperfdomain When the scmiperfdomain module was unloaded, a segmentation fault occurred. In the test system provided to the system under test, the power-domain-cells...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: possible double-free of cctx-remoteheap The function fastrpcinitcreatestaticprocess may free the cctx-remoteheap on the errmap path, but does not clear the pointer to it. Later, the function fastrpcrpmsgremove may...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mm: Fixed a livelock/fasting problem caused by hmmrangefault If hmmrangefault fails a foliotrylock in doswappage, and attempts to acquire the lock of a device-private folio for migration, the function will spin until it...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: xsk: Validates the MTU against the usable frame size when binding. The AFXDP binding currently accepts zero-copy pool configurations without verifying that the device’s MTU fits within the usable frame space provided by the UMEM...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: GPIB: LPVOUSB – fixed a memory leak that occurred when USB devices were disconnected.
