Astra Linux – Vulnerability in Qemu

A flaw was discovered in the USB redirector device usb-redir of QEMU. Small USB packets are combined into a single, large transfer request, in order to reduce overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array VLA on th...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-resv: Stop leaking data upon a failure of krealloc. Currently, when dmaresvgetfences fails, it will leak the previously allocated array if the fence iteration was restarted and kreallocarray failed. The old array must...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerabilities have been resolved: media: staging/intel-ipu3: Fixed error handling for setfmt operations. If an error occurs during the setfmt operation, do not overwrite the previous sizes with the invalid configuration. Without this patch, v4l2-compliance wil...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3: Error handling in gicpopulateppipartitions was fixed. The function ofgetchildbyname returns a node pointer with a refcount incremented. We should use ofnodeput on it when it is no longer needed. When kcalloc fails...

In the Linux kernel, the following vulnerability has been resolved: IB/hfi1: Fixed a memory leak in initcreditreturn. When dmaalloccoherent fails to allocate dd-crbasei.va, initcreditreturn should deallocate dd-crbase and dd-crbasei that were allocated earlier. Otherwise, those resources will nev...

Astra Linux – Vulnerability in libraw

LibRaw before 0.20-RC1 lacks a check for the thumbnail size range. This affects decoders/unpackthumb.cpp, postprocessing/memimage.cpp, and utils/thumbutils.cpp. For example, mallocsizeoflibrawprocessedimaget+T.tlength is used without validating T.tlength...

In the Linux kernel, the following vulnerabilities have been resolved: vlan: Fixed a memory leak in vlannewlink. The responsible commit added back a bug that I fixed in commit 9bbd917e0bec “vlan: fixed a memory leak in vlandevsetegresspriority”. If a memory allocation fails in vlanchangelink afte...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: virtionet: fixed device mismatch in devmkzalloc/devmkfree The initial rsshdr allocation uses virtiodevice-device, but virtnetsetqueues frees resources using netdevice-device. This device mismatch causes the following devres...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: media: cx23885 – Fixed a nullptrderef bug in bufferprepare and bufferfinish. When the driver calls cx23885riscbuffer to prepare the buffer, the function call dmaalloccoherent may fail, resulting in an empty buffer risc-cpu. Later...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: Integrity: Fixed memory leakage in the keyring allocation error path. Keys are allocated in the integrityinitkeyring function. However, if the keyring allocation fails, the allocated keys are not freed, resulting in memory lea...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerabilities have been resolved: drm: bridge/panel: Cleans up the connector when the bridge is detached If we do not call drmconnectorcleanup manually in panelbridgedetach, the connector will be cleaned up along with other DRM objects during the call to...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: codetag: debug: marking codetags for poisoned pages as empty When PGhwpoison pages are freed, they are treated differently in freepagesprepare. Instead of being released, they are isolated. The page allocation tag counters are...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: media: venus: vdec: A possible memory leak issue has been fixed. The implementation of venushelperallocdpbbufs allows for an early return on an error path when checking the ID from idaallocmin. This would prevent the earlier buff...

In the Linux kernel, the following vulnerability has been resolved: nfc: fixed a segfault in nfcgenldumpdevicesdone When kmalloc in nfcgenldumpdevices fails, nfcgenldumpdevicesdone causes a segfault as follows: KASAN: null-ptr-deref in range 0x0000000000000008-0x000000000000000f CPU: 0 PID: 25...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ext4: A potential memory leak has been fixed in ext4fcrecordregions. Since krealloc may return NULL, in this case, state-fcregions may not be freed by krealloc. However, state-fcregions is already set to NULL. This could lead to ...
