CVE-2026-53346

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> rust: arm64: set uwtable llvm module flag for CONFIG_UNWIND_TABLES<br /> <br /> Due to a rustc bug [1] the -Cforce-unwind-tables=y flag only emits the<br /> uwtable annotation for functions, but not for the module. This means<br /> that compiler-generated functions such as &amp;#39;asan.module_ctor&amp;#39; do not<br /> receive the uwtable annotation.<br /> <br /> When CONFIG_UNWIND_PATCH_PAC_INTO_SCS is enabled, this leads to boot<br /> failures because the dwarf information emitted for the kasan<br /> constructors is wrong, which causes the SCS boot patching code to<br /> patch the constructor in an illegal manner. Specifically, the paciasp<br /> instruction is patched, but the autiasp instruction is not. This<br /> mismatch leads to a crash when the constructor is called during boot.<br /> <br /> ==================================================================<br /> BUG: KASAN: global-out-of-bounds in do_basic_setup+0x4c/0x90<br /> Read of size 8 at addr ffffffe3cc7eb488 by task swapper/0/1<br /> <br /> Specifically the faulting instruction is the (*fn)() to invoke the<br /> constructor in do_ctors() of the init/main.c file.<br /> <br /> Once the fix lands in rustc, this flag can be made conditional on the<br /> rustc version. Note that passing the flag on a rustc with the fix<br /> present has no effect.<br /> <br /> [ The fix [1] has landed for Rust 1.98.0 (expected release on<br /> 2026-08-20).<br /> <br /> Thus add a version check as discussed.<br /> <br /> - Miguel ]<br /> <br /> [ Adjusted link and comment. - Miguel ]
