In the Linux kernel, the following vulnerability has been resolved: net: psample: Fixed an information leak in PSAMPLEATTRDATA. The psample open code uses nlaput to presumably avoid wiping the data with zeros, and instead overwrites it with packet data. This open coding does not clear the padding...

In the Linux kernel, the following vulnerability has been resolved: net/smc: Fixed a situation where a socket reference was dropped after the link group termination process. The smclgrterminate function drops the connslock after finding a connection in lgr-connsall, but before taking a reference ...

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

In the Linux kernel, the following vulnerability has been resolved: net/iucv: fixed the locking mechanism in .getsockopt. The functions iucvsocksetsockopt and iucvsocksetsobrowsable were mirrored, and the entire switch statement was wrapped within locksock/releasesock. The existing lock that only...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/tls: tlsswspliceread fails after an async decrypt failure. When an async decrypt fails, tlsdecryptdone records the error in ctx-asyncwait.err and calls tlserrabort, which stores the error in skerr. Both tlsswrecvmsg and...

In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: Reallocate the update replies for mismatched IDs. The ovsflowcmdnew function preallocates the optional reply skb before acquiring the ovsmutex, and before determining which existing flow will be updated. This is...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net/sched: fqpie: Clamp the default quantum to avoid signed overflow. The fqpieinit function sets q-quantum = pschedmtuqdiscdevsch without clamping it. A device with a very large MTU e.g., a dummy device with maxmtu == 0 and a...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/smc: A logic flaw in smcsetsockopt allows a local unprivileged user to cause a Denial of Service DoS by holding the socket lock indefinitely. A logic flaw in smcsetsockopt allows a local unprivileged user to cause a Denial of...

In the Linux kernel, the following vulnerability has been resolved: In the net/sched module, there is a issue where sfq: clamping the quantum value can lead to a signed overflow condition, causing a soft lockup. The sfqinit function sets q-quantum to pschedmtuqdiscdevsch unsigned. A device with a...
