CVE-2026-45993

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Add spectre boundry for syscall dispatch table The LoongArch syscall number is directly controlled by userspace, but does not have a arrayindexnospec boundry to prevent access past the syscall function pointer tables...

Astra Linux - уязвимость в linux, linux-5.10

In the Linux kernel, the following vulnerabilities have been resolved: vtioctl: fixed arrayindexnospec in vtsetactivate. arrayindexnospec ensures that an out-of-bounds value is set to zero on the transient path. Reducing this value by one afterward causes a transient integer underflow. vsa.consol...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: RISCV: Sanitizing syscall table indexing under speculation The syscall number is a user-controlled value used to index into the syscall table. Use arrayindexnospec to clamp this value after the bounds check, to prevent speculativ...

Astra Linux - уязвимость в linux-6.1, linux-5.10, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Use arrayindexnospec with indices that come from the guest. min and destid are guest-controlled indices. Using arrayindexnospec after the bounds checks helps to mitigate speculative execution side-channels...

SUSE CVE-2026-31781

In the Linux kernel, the following vulnerability has been resolved: drm/ioc32: stop speculation on the drmcompatioctl path The drm compat ioctl path takes a user controlled pointer, and then dereferences it into a table of function pointers, the signature method of spectre problems. Fix this up b...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: iouring: prevents reg-wait speculation. By using ENTEREXTARGREG instead of passing a user pointer along with arguments for the waiting loop, the user can specify an offset within a pre-mapped region of memory. In this case, offse...

Linux Distros Unpatched Vulnerability : CVE-2026-31781

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - drm/ioc32: stop speculation on the drmcompatioctl path The drm compat ioctl path takes a user controlled pointer, and then dereferences it into a table of...

CVE-2026-23354

In the Linux kernel, the following vulnerability has been resolved: x86/fred: Correct speculative safety in fredextint arrayindexnospec is no use if the result gets spilled to the stack, as it makes the believed safe-under-speculation value subject to memory predictions. For all practical purpose...

kernel: protect the fetch of ->fd[fd] in do_dup2() from mispredictions

In the Linux kernel, the following vulnerability has been resolved: protect the fetch of -fdfd in dodup2 from mispredictions both callers have verified that fd is not greater than -maxfds; however, misprediction might end up with tofree = fdt-fdfd; being speculatively executed. That's wrong for t...

SUSE CVE-2024-58000

In the Linux kernel, the following vulnerability has been resolved: iouring: prevent reg-wait speculations With ENTEREXTARGREG instead of passing a user pointer with arguments for the waiting loop the user can specify an offset into a pre-mapped region of memory, in which case the offset, offset ...

CVE-2024-58000

CVE-2024-58000 affects the Linux kernel Io_uring reg-wait path. The root cause is speculative execution on a kernel array indexed by user input when using ENTER_EXT_ARG_REG, which could interpret an offset into a pre-mapped memory region as an argument. The documented fix is to prevent speculativ...
