Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: marvell: prestera: Fixed a NULL dereferencing on devlinkalloc failure. devlinkalloc may return NULL when allocation fails, but presteradevlinkalloc will unconditionally call devlinkpriv on the returned pointer. This leads to...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd: Check the event before enabling it to avoid a General Protection Fault GPF. On AMD machines, cpuc-eventsidx can become NULL due to a subtle race condition with NMI-throttle-x86pmustop. Check if the event is NULL in...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/i915/gvt: fixed the issue where gvt debugfs destruction occurred unexpectedly. When gvt debugfs is destroyed, it is necessary to perform a check to ensure that the DRM minor’s debugfs root is still available. Otherwise, in...

In the Linux kernel, the following vulnerability has been resolved: remoteproc: qcom: q6v5: Fixed a potential null-ptr-deref in q6v5wcssinitmmio The q6v5wcssinitmmio function will call platformgetresourcebyname, which may fail and return NULL. The devmioremap function will use res-start as an...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: Added a missing NULL pointer check for the pingpong interface. This check is almost always performed in dpuencoderphyswbsetupctl, but in a single location, the check is missing. Also, use convenient locals variables...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: drm/ttm: Added a check to avoid dereferencing of a null pointer during swapping. The following code has been added to prevent null pointer dereferencing: 90.002283 General protection fault, likely for non-canonical addresses...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211hwsim: Fixed possible NULL dereferencing. In the call to mac80211hwsimselecttxlink, the sta pointer might be NULL. Therefore, it is necessary to check that it is not NULL before accessing it...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: Tracing: Fixed a null pointer dereference in the tracingerrlogopen function. This issue occurs when the function does not call seqopen if the file is opened only with write permissions. As a result, file-privatedata remains...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RDMA/cxgb4: A potential null-ptr-deref occurred in passestablish. If getepfromtid fails to find a non-NULL value for ep, ep will be dereferenced later, regardless of whether it is empty. This patch adds a simple sanity check to f...
