Astra Linux – Vulnerability in Netty

In Netty 4.1.x before 4.1.46, the ZlibDecoders allowed unbounded memory allocation when decoding Zlib-encoded byte streams. An attacker could send a large Zlib-encoded byte stream to the Netty server, forcing the server to allocate all of its available memory to a single decoder...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: Net: Atlantic – Eliminate double-free operations in error handling logic. The driver has a logic flaw in ring data allocation/free. In this flaw, aqringfree may be called multiple times within the same ring. This can occur whe...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: btrfs: In the zone operation, the code must traverse devices under the chunkmutex in btrfscanactivatezone. The btrfscanactivatezone function can be called with the devicelistmutex already held, which could lead to a deadlock. ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Networking: DSA: Felix: Fixed possible NULL pointer dereferencing. As a possible failure during allocation, kzalloc may return a NULL pointer. Therefore, it is better to check for ‘sgi’ to prevent the dereferencing of a NULL...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mm/hugememory: Fixed the memory leak associated with xarray nodes. If the xassplitalloc function fails to allocate the necessary nodes to complete the splitting of the xarray entries, it sets the xastate to -ENOMEM. This triggers...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: The block operation involving GFPNOIO around the sysfs-store function. The sysfs-store function is called with the queue frozen. Meanwhile, there are several -store callbacks such as updatenrrequests, wbt, scheduler that use...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

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: ima: Fixed a potential memory leak in imainitcrypto. If the SHA1 template is unable to be allocated, IMA fails to initialize and exits without freeing the imaalgoarray. Adding the necessary kfree call for imaalgoarray will preven...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: phy: qcom: at803x: fix kernel panic with at8031probe When reworking and splitting the at803x driver, a NULL dereference bug was identified in the function that splits at803x PHYs. In this bug, the variable priv is referenced...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: cifs: Fixed the issue where the smbd connection was lost and destroyed when the MR allocation failed. If the MR allocation fails, the smbdDestroy function will return NULL, and the connection information will be leaked. We need t...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: LoongArch: Fixed missing NULL checks for kstrdup 1. Replaced “offindnodebypath"/"” with “ofroot” to avoid multiple calls to “ofnodeput”. 2. Fixed a potential kernel error during early boot when memory allocation fails while...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: mmc: toshsd: fixed the return value check in mmcaddhost The mmcaddhost function may return an error. If we ignore its return value, the memory allocated in mmcallochost will be leaked, leading to a kernel crash due to the...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Fixed a potential data race in the PCM memory allocation helpers The PCM memory allocation helpers include a sanity check to prevent too many buffer allocations. However, this check is performed without proper locking,...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: xen/privcmd: Fixed a possible warning in privcmdioctlmmapresource. Since ‘kdata.num’ is a user-controlled data, if the user attempts to allocate memory larger than MAXORDER, then kcalloc will fail. This will also generate a stack...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: crypto: comp – Use the same definition for the context alloc and free operations. In commit 42d9f6c77479 “crypto: acomp – Move the scomp stream allocation code into acomp”, the cryptoacompstreams struct was designed to rely on th...

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

In the Linux kernel, the following vulnerability has been resolved: ext4: A potential memory leak has been fixed in ext4fcrecordregions.
