CVSS 3.1
5.5 mediumCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2024-42247
Medium (5.5) in linux linux kernel. EPSS 0.7% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
wireguard: allowedips: avoid unaligned 64-bit memory accesses
On the parisc platform, the kernel issues kernel warnings because
swap_endian() tries to load a 128-bit IPv6 address from an unaligned
memory location:
Kernel: unaligned access to 0x55f4688c in wg_allowedips_insert_v6+0x2c/0x80 [wireguard] (iir 0xf3010df)
Kernel: unaligned access to 0x55f46884 in wg_allowedips_insert_v6+0x38/0x80 [wireguard] (iir 0xf2010dc)
Avoid such unaligned memory accesses by instead using the
get_unaligned_be64() helper macro.
