CVE-2026-72502

In the Linux kernel, the following vulnerability has been resolved: tcp: ipv6: clamp default adverting MSS to avoid GSOBYFRAGS 0xFFFF When MTU is large, ip6defaultadvmss can return IPV6MAXPLEN 65535. This is interpreted by TCP as mssclamp, allowing the MSS to reach 65535. However, 0xFFFF is also...

Ubuntu 18.04 LTS / 20.04 LTS : Linux kernel vulnerabilities (USN-6767-1)

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6767-1 advisory. Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of- bounds read vulnerability. An attacker...

Amazon Linux 2 : kernel, --advisory ALAS2KERNEL-5.10-2024-053 (ALASKERNEL-5.10-2024-053)

The version of kernel installed on the remote host is prior to 5.10.210-201.852. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2024-053 advisory. dmtablecreate in drivers/md/dm-table.c in the Linux kernel through 6.7.4 can attempt to in alloctargets...

Important: kernel

Issue Overview: dmtablecreate in drivers/md/dm-table.c in the Linux kernel through 6.7.4 can attempt to in alloctargets allocate more than INTMAX bytes, and crash, because of a missing check for struct dmioctl.targetcount. CVE-2023-52429 A flaw was found in the smb client in the Linux kernel. A...

CVE-2023-52435

A flaw was found in the Linux kernel’s net/core/skbuff.c subsystem. The GSOBYFRAGS is a forbidden value and allows the following computation in skbsegment to reach it. The : mss = mss partialsegs and many initial mss values can lead to a bad final result. Limit the segmentation so that the new ms...

CVE-2023-52435

In the Linux kernel, the following vulnerability has been resolved: net: prevent mss overflow in skbsegment Once again syzbot is able to crash the kernel in skbsegment 1 GSOBYFRAGS is a forbidden value, but unfortunately the following computation in skbsegment can reach it quite easily : mss = ms...

CVE-2023-52435 net: prevent mss overflow in skb_segment()

In the Linux kernel, the following vulnerability has been resolved: net: prevent mss overflow in skbsegment Once again syzbot is able to crash the kernel in skbsegment 1 GSOBYFRAGS is a forbidden value, but unfortunately the following computation in skbsegment can reach it quite easily : mss = ms...

CVE-2023-52435

CVE-2023-52435 affects the Linux kernel’s net/ skb_segment() and can overflow MSS when computing mss = mss * partial_segs, risking a crash (e.g., GSO_BY_FRAGS) and triggering NULL pointer dereferences in some traces. The fix adds a guard to ensure the new MSS is smaller than GSO_BY_FRAGS, prevent...
