SUSE CVE-2025-39793

In the Linux kernel, the following vulnerability has been resolved: iouring/memmap: cast nrpages to sizet before shifting If the allocated size exceeds UINTMAX, then it's necessary to cast the mr-nrpages value to sizet to prevent it from overflowing. In practice this isn't much of a concern as th...

UBUNTU-CVE-2023-53309

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: Fix integer overflow in radeoncsparserinit The type of size is unsigned, if size is 0x40000000, there will be an integer overflow, size will be zero after size = sizeofuint32t, will cause uninitialized memory to be...

CVE-2023-53309

CVE-2023-53309 affects the Linux kernel’s drm/radeon path. The vulnerability stems from an overflow in radeon_cs_parser_init: the size field is unsigned, and if size equals 0x40000000, the calculation size *= sizeof(uint32_t) overflows, causing size to wrap to zero and leading to use of uninitial...
