Linux Distros Unpatched Vulnerability : CVE-2026-53346

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - rust: arm64: set uwtable llvm module flag for CONFIGUNWINDTABLES Due to a rustc bug 1 the -Cforce- unwind-tables=y flag only emits the uwtable annotation for...

CVE-2026-53346

A flaw was found in the Linux kernel. A bug in the Rust compiler's handling of unwind tables for ARM64 architecture can lead to incorrect debugging information for kernel AddressSanitizer KASAN constructors. When a specific security feature CONFIGUNWINDPATCHPACINTOSCS is enabled, this error cause...

CVE-2026-53343

A flaw was found in the Linux kernel. On ARMv5 systems configured with Kernel Address Sanitizer KASAN for virtual memory allocated VMAP stack shadow, a memory access operation could attempt to read data from an unaligned memory address. This unaligned access leads to an alignment exception, causi...

CVE-2026-53349

CVE-2026-53349 concerns the Linux kernel netfilter nf_conntrack component where a stale exp->expectfn pointer can survive module removal (e.g., nf_nat_h323) and be invoked later, causing a crash (Oops) in init_conntrack when a connection arrives. The fix adds nf_ct_helper_expectfn_destroy() to...

CVE-2026-53346

In CVE-2026-53346, affected software is the Linux kernel on arm64, where a rustc bug prevents -Cforce-unwind-tables=y from annotating the module, leaving the uwtable flag missing for module constructors (e.g., asan.module_ctor). When CONFIG_UNWIND_PATCH_PAC_INTO_SCS is enabled, this mismatch can ...

CVE-2026-53343

The CVE-2026-53343 entry documents a Linux kernel ARM vulnerability patch: in configurations with KASAN_VMALLOC and VMAP_STACK, a dummy read from the KASAN VMAP shadow in __switch_to() used an unaligned word load (ldr) which can fault on ARMv5 and crash ARM926/VersatilePB; the fix switches to a b...
