CVE-2026-89716 zram: validate deflate params

In the Linux kernel, the following vulnerability has been resolved: zram: validate deflate params We must validate user-supplied deflate winbits before we pass it to zlibdeflateworkspacesize, which triggers BUGON if winbits value is outside of valid ranges...

CVE-2026-89716

In the Linux kernel, the following vulnerability has been resolved: zram: validate deflate params We must validate user-supplied deflate winbits before we pass it to zlibdeflateworkspacesize, which triggers BUGON if winbits value is outside of valid ranges...

CVE-2026-89716

CVE-2026-89716 affects the Linux kernel's zram module. User-supplied deflate winbits are passed to zlib_deflate_workspacesize() without validation; if the value falls outside the valid range, a BUG_ON() is triggered, resulting in a kernel bug/panic. The fix validates the winbits parameter before ...

CVE-2026-89701

In the Linux kernel, the following vulnerability has been resolved: nfsd: validate nseconds in TIMEDELEG decode paths The xdrgen-based TIMEDELEGACCESS and TIMEDELEGMODIFY decode arms store a raw uint32t nseconds directly into tvnsec without enforcing nseconds NSECPERSEC. The legacy...

CVE-2026-89695

A Denial of Service vulnerability in the Linux kernel's NFSD (Network File System Daemon) component. The nfsd4_decode_posixacl() function reads a client-supplied u32 entry count without capping it, passing it directly to an O(n²) bubble sort (sort_pacl_range()). A remote attacker can send a craft...

EUVD-2026-76578

In the Linux kernel, the following vulnerability has been resolved: nfsd: reject out-of-range nseconds in NFSv3 SETATTR and create ops A client can send an NFSv3 SETATTR, CREATE, MKDIR, SYMLINK or MKNOD carrying an atime or mtime whose nseconds field is out of range. The value is well-formed on t...

CVE-2026-89666

CVE-2026-89666 affects the Linux kernel's nfsd (NFS server daemon). A client can send an NFSv3 SETATTR, CREATE, MKDIR, SYMLINK, or MKNOD carrying an atime or mtime whose nseconds field is out of range —it decodes as a valid uint32 but is not a valid timespec64. Nothing in the setattr path clamps ...

CVE-2026-89584

In the Linux kernel, the following vulnerability has been resolved: block: validate user space vectors during extraction The bio-based drivers don't necessarily check the alignment split, and stacking block drivers don't always handle a misalignment detected after submitting the bio. Validate use...

CVE-2026-89571

This is an out-of-bounds read in the Linux kernel's CXL (Compute Express Link) features subsystem. The fwctl_cmd_rpc() function copies user-supplied data into a fixed-size buffer, but the downstream cxlctl_set_feature() callback validates the user-controlled op_size only from below, never against...
