Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: Fixed the issue where kvzalloc was used instead of statekcalloc. The adrenoshowobject function is problematic. It reallocates the pointer it passes on during the first call, when the data is encoded as ascii85. This...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: netpoll: Fixed a deadlock in memory allocation under spinlock. A deadlock occurred in the refillskbs function, where memory allocation while holding skbpool-lock could trigger a recursive lock acquisition attempt. This deadlock...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: skmsg: The allocskmsg function can be called from a non-sleepable context. The skpsockverdictrecv function uses rcureadlock protection. We need the callers to pass a gfpt argument to avoid issues. The report from syzbot stated:...

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, Linux 5.10

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 ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: vxlan: Fixed memory leaks in the error path. The memory allocated by vxlanvnigroupinit is not freed during the error path, leading to memory leaks 1. This issue was fixed by calling vxlanvnigroupuninit during the error path. T...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Driver: soc: xilinx: fixed a memory leak in xlnxaddcbfornotifyevent. The kfree function should be called when memory fails to be allocated for cbdata in xlnxaddcbfornotifyevent. Otherwise, a memory leak will occur; therefore,...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Check kzalloc in lpfcsli4cgnparamsread. If kzalloc fails in lpfcsli4cgnparamsread, then we rely on lpfcreadobject’s routine to perform a NULL check on pdata. Currently, an early return error is thrown from...
