In the Linux kernel, the following vulnerability has been resolved: net: atlantic: fix fragment overflow handling in RX path The atlantic driver can receive packets with more than MAX_SKB_FRAGS (17) fragments when handling large multi-descriptor packets. This causes an out-of-bounds write in skb_add_rx_frag_netmem() leading to kernel panic. The issue occurs because the driver doesn't check the total number of fragments before calling skb_add_rx_frag(). When a packet requires more than MAX_SKB_FRAGS fragments, the fragment index exceeds the array bounds. Fix by assuming there will be an extra frag if buff->len > AQ_CFG_RX_HDR_SIZE, then all fragments are accounted for. And reusing the existing check to prevent the overflow earlier in the code path. This crash occurred in production with an Aquantia AQC113 10G NIC.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For Debian 11 bullseye, these problems have been fixed in version     6.1.159-1~deb11u1.  This update also fixes several bugs reported to     Debian.  It additionally includes many more bug fixes from stable     update 6.1.159.

    We recommend that you upgrade your linux-6.1 packages.

    For the detailed security status of linux-6.1 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/linux-6.1

  - net: atlantic: fix fragment overflow handling in RX path The atlantic driver can receive packets with more     than MAX_SKB_FRAGS (17) fragments when handling large multi-descriptor packets. This causes an out-of-     bounds write in skb_add_rx_frag_netmem() leading to kernel panic. The issue occurs because the driver     doesn't check the total number of fragments before calling skb_add_rx_frag(). When a packet requires more     than MAX_SKB_FRAGS fragments, the fragment index exceeds the array bounds. Fix by assuming there will be     an extra frag if buff->len > AQ_CFG_RX_HDR_SIZE, then all fragments are accounted for.
