Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fixed the issue of loading the RxGK token to check bounds. The rxrpcpreparsexdryfsrxgk function reads the raw key length and ticket length from the XDR token as u32 values. It then rounds up each value by 4 before using th...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: smb: server: The use of smbdirectsocket.sendio.bcredits has been addressed. It turns out that our code will corrupt the stream of reassabled data transfer messages when we trigger an immediate empty send. To fix this issue, we wi...

Astra Linux - уязвимость в u-boot

There exists an unchecked length field in UBoot. The U-Boot DFU implementation does not bind the length field in USB DFU download setup packets, and it does not verify that the transfer direction corresponds to the specified command. Consequently, if a physical attacker creates a USB DFU download...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: hwmon: tps53679 Fixed array access with zero-length block reads. i2csmbusreadblockdata can return 0, indicating a zero-length read. When this occurs, tps53679identifychip accesses bufret - 1, which is actually buf-1. This mean...
