wvWare wv through 1.2.9 contains a stack-based out-of-bounds read vulnerability in wvGetPAPX FKP and wvGetCHPX FKP caused by an unvalidated FKP run count. Attackers can supply a crafted .doc file with a large crun value to read kilobytes past the 512-byte stack buffer, crashing applications like...

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject non-negative offsets in stack slot obj get spi bpf get spi computes -off - 1 / BPF REG SIZE using C division, which truncates toward zero. For off == 0, this produces spi 0, the same index used by the valid stack slot...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the BPF subsystem where program-allocated objects can own other local objects via referenced kptrs. The function bpf obj free fields follows these pointers through bpf...

CVE-2026-98528: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: gpio: cdev: fix kernel stack leak to user-space in error path If we fail to acquire the GPIO chip guard in gpiodesctolineinfo, we return immediately before zeroing the info struct we'll end up passing to the user-space later in...

Linux Kernel Security Vulnerabilities

Versions of the Linux kernel prior to 6.12.113, 6.18.56, and 7.2.10 contain security vulnerabilities. These vulnerabilities stem from the viovcc structure used in vccsendctl, where the packet associated with the stack allocation is not fully initialized. As a result, the tag.stypeenv field is not...

CVE-2026-98853: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net: gso: limit recursive IP-in-IP segmentation IP-in-IP GSO can re-enter inetgsosegment or ipv6gsosegment for each nested IP header. encaplevel tracks header bytes, not callback depth, so a deep chain can exhaust the kernel stac...

CVE-2026-98466: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Transfer the hyp stack pages out of the host stage-2 fixhostownership walks only the linear-map alias of each memblock region, and the per-CPU hyp stack, mapped in the private VA range for its guard page, has none. Wa...

Linux Kernel Security Vulnerabilities

The Linux kernel version 3.13 contains a security vulnerability. This vulnerability arises from IP-in-IP GSO, which allows each nested IP header to repeatedly enter inetgsosegment or ipv6gsosegment. However, encaplevel only tracks the header bytes and not the callback depth. Deeply nested chains...
