Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: net/sun382586: A potential memory leak has been fixed in sun382586sendpacket. In sun382586sendpacket, if skb-len is too long, it returns NETDEVTXOK without freeing the skb. To address this issue, add a call to devkfreeskb to...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: Wifi: ath9khtc: Use skbsetlength to reset urb before resubmitting it. Syzbot points out that skbtrim has a sanity check on the existing length of the skb; this length might not be initialized in some error-prone situations. The...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: can: j1939: j1939sessionnew: fix skb reference counting Since j1939sessionskbqueue performs an additional skbget for each new skb, doing the same for the initial instance in j1939sessionnew will prevent refcount underflow. mkl:...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcicore: Fixed the issue where no check was performed to determine whether skb actually contained an ACL header. Otherwise, the code might attempt to access uninitialized/invalid memory beyond the valid skb-data...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fixed a segmentation fault in rxecompqueuepkt. In rxecompqueuepkt, an incoming response packet is enqueued into the resppkts queue. Then, it is decided whether to run the completer task inline or schedule it. Finally, t...

In the Linux kernel, the following vulnerability has been resolved: atm: idt77252: prevent use after free in dequeuerx We cannot dereference “skb” after calling vcc-push, because the skb is released...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: net: vertexcom: mse102x: Fixed a possible double-free of TXskb. The scope of TXskb is broader than just mse102xtxframespi; therefore, if the TXskb memory needs to be expanded, we should free the temporary skb instead of the...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: octeonep: Added handling of SKB allocation failures in octepoqprocessrx. The buildskb function returns NULL in case of a memory allocation failure. Therefore, this behavior should be handled within octepoqprocessrx to prevent NUL...
