CVE-2026-90141

A flaw was found in the Linux kernel's IP Virtual Server IPVS FTP helper. A remote attacker could exploit an integer overflow vulnerability in the ipvsftpgetaddrport function by sending a specially crafted FTP PASV/EPSV response. This could cause the FTP helper to configure data connections with...

kernel: ipvs: clear IPv4 options after rebasing tunnel ICMP errors

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. When processing Internet Control Message Protocol ICMP errors for tunneled packets, the system can incorrectly use a stale IPv4 option offset. A remote attacker could exploit this by sending a specially crafted ICMP packet,...

kernel: ipvs: clear the svc scheduler ptr early on edit

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. During the ipvseditservice operation, the svc-scheduler pointer is cleared too late when unbinding an old scheduler. This improper handling allows packets to access previously freed scheduler data, leading to a use-after-fre...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ipvs: Avoid out-of-bounds write in ipvsnaticmp Sashiko warns that a local attacker can modify the packet while it is being processed by IPVS. Some parts of the code read the IP ihl field multiple times, which can lead to...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ipvs: Use the parsed transport offset in the TCP state lookup. The TCP state handling processes the skb again to find the TCP header. For IPv6, it uses sizeofstruct ipv6hdr. Meanwhile, the surrounding IPVS code has already parsed...

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

In the Linux kernel, the following vulnerability has been resolved: ipvs: Properly dereferencing pe in ipvsaddservice. Use pe directly to resolve the sparse warning: net/netfilter/ipvs/ipvsctl.c:1471:27: warning: dereference of noderef expression...

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: ipvs: Do not propagate the “one-packet” flag to synced connections. Synced connections can be created before their destination exists. When the destination is later added, ipvsbinddest copies the connection flags from the...

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

In the Linux kernel, the following vulnerability has been resolved: ipvs: fix ipv4 null-ptr-deref in route error path The IPv4 code path in ipvsgetoutrt calls dstlinkfailure without ensuring skb-dev is set, leading to a NULL pointer dereference in fibcomputespecdst when ipv4linkfailure attempts t...
