Astra Linux - уязвимость в linux-5.10, linux
In the Linux kernel, the following vulnerability has been resolved: gsmi: fixed a null dereference in gsmigetvariable. We can access EFI variables without retrieving the attributes; therefore, we must allow this behavior in gsmi. Commit 859748255b43 “efi: pstore: Omit efivars caching EFI varstore...
Astra Linux - уязвимость в linux-5.10
In the Linux kernel, the following vulnerability has been resolved: firmware: qcom: uefisecapp: fix efivars registration race Since the conversion to using the TZ allocator, the efivars service is registered before the memory pool has been allocated, something which can lead to a NULL-pointer...
CVE-2025-8860 Qemu-kvm: uefi-vars: information disclosure vulnerability in uefi_vars_write callback
A flaw was found in QEMU in the uefi-vars virtual device. When the guest writes to register UEFIVARSREGBUFFERSIZE, the .write callback uefivarswrite is invoked. The function allocates a heap buffer without zeroing the memory, leaving the buffer filled with residual data from prior allocations. Wh...
