In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fixed the publication race in priv-channelstats. The mlx5echannelstatsalloc function publishes a new entry to priv-channelstats, and then increments priv-statsnch as a publication token. However, neither operation...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: ASoC: qcom: q6apm: fixed a NULL pointer dereferencing in graphcallback. When q6apmfreefragments is called, it frees rxdata.buf/txdata.buf and sets them to NULL under graph-lock. A late DSP buffer-done response can cause issues...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: pfcp: Allocate per-cpu tstats for PFCP netdevs PFCP uses devgettstats64 as its ndogetstats64 callback. However, pfcplinksetup does not request NETDEVPCPUSTATTSTATS. As a result, the net core leaves dev-tstats as NULL for PFC...
