In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: fixed a double-free in sidpminit When the allocation of adev-pm.dpm.dynstate.vddcDependenceondispclk.entries fails, amdgpufreeextendedpowertable is called to free some fields of adev. However, when the control flow...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: rapidio: fixed a possible Use-after-Allocation UAF issue when kfifoalloc fails. If kfifoalloc fails in mportcdevopen, it jumps to errfifo and simply frees the priv object. However, since priv remains in chdev-filelist, traversal ...

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: 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, 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...

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 Firefox

In the lginit function, if several allocations succeed, but one fails, an uninitialized pointer would be freed even though it was never actually allocated. This vulnerability affects Firefox versions earlier than 102...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: xfs: removed calls to xchkxfiledescr macros. The xchkxfiledescr macros use kasprintf, which may fail to allocate memory if the formatted string is longer than 16 bytes or whatever value nofail currently guarantees. Some of the...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fixed a potential double-free in fsanycreategroups. When kcalloc is called for ft-g and succeeds, but kvzalloc is called for in and fails, fsanycreategroups will free ft-g. However, its caller, fsanycreatetable, will...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: ASoC: pxa: fixed a null-pointer dereference in filter The kasprintf function would return a NULL pointer when kmalloc fails to allocate memory. It is necessary to check the return pointer before calling strcmp...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: Staging: vt6655 – Fixed some erroneous memory cleanup loops. In some initialization functions of this driver, memory is allocated using ‘i’ as an index variable, with the value increasing from 0. The “Fixes” section includes...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net: Handling of integer overflows in kmallocreserve The committed change was as follows: c ptr = kmallocsize; if ptr size = ksizeptr; size = kmallocsizeroundupsize; ptr = kmallocsize; This caused various crashes, as reported ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: TCP: Fixed handling of refcnt in inethashconnect. syzbot reported a warning in sknullsdelnodeinitrcu. The commit 66b60b0c8c4a “dccp/tcp: Unhash sk from ehash for tb2 allocation failure after checkestablished” attempted to fix ...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: qlogic: qlcnic: A NULL pointer dereference was fixed in qlcnic83xxaddrings. In qlcnic83xxaddrings, the indirect function ahw-hwops-allocmbxargs is called to allocate memory for cmd.req.arg. A dereference of this variable...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ASoC: SDCA: Added a check for allocation failure for the Entity name. Currently, the findsdcaentityiot function can allocate a string for the Entity name, but it does not check whether the allocation was successful. Add a missing...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ASoC: imx-hdmi: Fixed a reference count leak in imxhdmiprobe. The offinddevicebynode function takes a reference; we should use putdevice to release that reference. When devmkzalloc fails, there is no putdevice function available,...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: clk: zynq – Prevent null pointer dereferencing caused by kmalloc failure The kmalloc function in zynqclksetup will return null if physical memory runs out. As a result, if we use snprintf to write data to a null address, the null...
