In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed a null pointer dereference in resolveprogtype for BPFPROGTYPEEXT. When loading an EXT program without specifying attr-attachprogfd, the prog-aux-dstprog will be null. At this time, calling resolveprogtype anywhere will...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: dpaa: Padding packets to ETHZLEN When sending packets that are less than 60 bytes, up to three bytes of the buffer following the data may be leaked. Avoid this by extending all packets to ETHZLEN, ensuring that nothing is...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: added more sanity checks to qdiscpktleninit. One of the approaches handles SKBGSODODGY, assuming that skb-len is greater than hdrlen. The function virtionethdrtoskb does not fully dissect TCP headers; it only ensures that th...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ax25: Fixed the reference count leak issue of the netdevice object. There is a reference count leak issue with the object netdevice in the function ax25devdevicedown. When the ax25 device is being shut down, the ax25devdevicedown...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: liquidio: The handling of NULL pointers in liovfrepcopypacket was adjusted. In liovfrepcopypacket, pginfo-page is compared to a NULL value, but it is then unconditionally passed to skbaddrxfrag, which seems strange and could lead...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: r8169: Fixed possible ring buffer corruption due to fragmented Tx packets. An issue was discovered in the RTL8125b driver when transmitting small, fragmented packets. Invalid entries were inserted into the transmit ring buffer,...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ppp: Rejects packets that are claimed to be LCP packets but are actually malformed packets. Since pppasyncencode assumes that the packets are valid LCP packets with codes from 1 to 7 inclusive, add pppcheckpacket to ensure that t...
