CVE-2022-50167 bpf: fix potential 32-bit overflow when accessing ARRAY map element

In the Linux kernel, the following vulnerability has been resolved: bpf: fix potential 32-bit overflow when accessing ARRAY map element If BPF array map is bigger than 4GB, element pointer calculation can overflow because both index and elemsize are u32. Fix this everywhere by forcing 64-bit...

CVE-2022-50093

CVE-2022-50093 affects the Linux kernel IOMMU VT-d code. The issue arises from using arch_test_bit() with a possibly invalid first argument when NUMA is disabled, causing a potential wild memory access after node_online() returns NUMA_NO_NODE. The fix adds an explicit check for node != NUMA_NO_NO...

CVE-2022-50012 powerpc/64: Init jump labels before parse_early_param()

In the Linux kernel, the following vulnerability has been resolved: powerpc/64: Init jump labels before parseearlyparam On 64-bit, calling jumplabelinit in setupfeaturekeys is too late because static keys may be used in subroutines of parseearlyparam which is again subroutine of earlyinitdevtree...

CVE-2025-38065

In the Linux kernel, the following vulnerability has been resolved: orangefs: Do not truncate file size 'len' is used to store the result of isizeread, so making 'len' a sizet results in truncation to 4GiB on 32-bit systems...

CVE-2025-38065 orangefs: Do not truncate file size

Rubber Mallet: a Study of High Frequency Localized Bit Flips and Their Impact on Security

The increasing density of modern DRAM has heightened its vulnerability to Rowhammer attacks, which induce bit flips by repeatedly accessing specific memory rows. This paper presents an analysis of bit flip patterns generated by advanced Rowhammer techniques that bypass existing hardware defenses...

Bias Variation Compensation in Perimeter-Gated SPAD TRNGs

Random number generators that utilize arrays of entropy source elements suffer from bias variation BV. Despite the availability of efficient debiasing algorithms, optimized implementations of hardware friendly options depend on the bit bias in the raw bit streams and cannot accommodate a wide BV...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: The current directory offset allocator based on mtreealloccyclic stores the next offset value to be returned in octx-nextoffset. This mechanism typically returns values that increase monotonically over time. Eventually, however,...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: filemap: Avoid truncating the 64-bit offset to 32 bits. On 32-bit kernels, the folioseekholedata function inadvertently truncated a 64-bit value to 32 bits, which could lead to an infinite loop when writing to an xfs filesystem...
