Astra Linux – vulnerability in linux-5.10, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: e100: Fix possible use after free in e100xmitprepare In e100xmitprepare, if we cannot map the skb, then return -ENOMEM; thus, e100xmitframe returns NETDEVTXBUSY and the upper layer resends the skb. However, the skb has already be...

In the Linux kernel, the following vulnerability has been resolved: In the BPF code, ensure that skb-len != 0 when redirecting a packet to a tunneling device. The syzkaller function managed to trigger another case where skb-len == 0 when entering devqueuexmit. WARNING: CPU: 0, PID: 2470; Location...

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

In the Linux kernel, the following vulnerability has been resolved: net: atm: fixed the use after free in lecsend The -send operation frees the skb object; therefore, the length of the object should be saved before calling -send to avoid a use after free situation...

Astra Linux - vulnerability in linux

In the Linux kernel, the following vulnerability has been resolved: net: cdceem: fix tx fixup skb leak When usbnet transmits a skb, it is fixed via eemtxfixup. If skbcopyexpand fails, it returns NULL; consequently, usbnetstartxmit has no chance to free the original skb. The fix involves freeing t...

In the Linux kernel, the following vulnerability has been resolved: net: dlink: handle copythresh allocation failure The driver did not handle the failure of netdevallocskbip-align. If the allocation fails, dereferencing skb-protocol could lead to a NULL pointer dereference. This patch attempts t...

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

In the Linux kernel, the following vulnerability has been resolved: can: j1939: j1939sessionnew: fix skb reference counting Since j1939sessionskbqueue performs an additional skbget operation for each new skb, doing the same operation for the initial skb in j1939sessionnew will prevent refcount...

Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: net: vertexcom: mse102x: Fix possible double free of TX skb The scope of the TX skb is wider than just mse102xtxframespi; therefore, if the TX skb buffer needs to be expanded, we should free the temporary skb rather than the...

In the Linux kernel, the following vulnerability has been resolved: can: j1939: fixed Use-after-Free, failed to increment the ref count of the skb while it was in use. This patch addresses a Use-after-Free issue identified by the syzbot. The problem arises when a skb is taken from the per-session...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: ieee802154: at86rf230: Stop leaking the skb structures. Upon an error, the ieee802154xmitcomplete helper function is not called. Only ieee802154wakequeue is called manually. In the Tx phase, the skb structure is leaked. Leas...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: nfc: fdp: Fixed a potential memory leak in fdpncisend. The fdpncisend function calls fdpncii2cwrite, which does not free the skb object after its execution. As a result, when fdpncii2cwrite is completed, the skb object will...
