GHSA-5793-WFXR-J725
Vulnerability from github – Published: 2024-09-27 15:30 – Updated: 2025-11-04 00:31In the Linux kernel, the following vulnerability has been resolved:
dma-buf: heaps: Fix off-by-one in CMA heap fault handler
Until VM_DONTEXPAND was added in commit 1c1914d6e8c6 ("dma-buf: heaps: Don't track CMA dma-buf pages under RssFile") it was possible to obtain a mapping larger than the buffer size via mremap and bypass the overflow check in dma_buf_mmap_internal. When using such a mapping to attempt to fault past the end of the buffer, the CMA heap fault handler also checks the fault offset against the buffer size, but gets the boundary wrong by 1. Fix the boundary check so that we don't read off the end of the pages array and insert an arbitrary page in the mapping.

GHSA-5VJG-59F8-HCQ8
Vulnerability from github – Published: 2025-05-02 18:31 – Updated: 2025-11-10 18:30In the Linux kernel, the following vulnerability has been resolved:
ext4: fix another off-by-one fsmap error on 1k block filesystems
Apparently syzbot figured out that issuing this FSMAP call:
struct fsmap_head cmd = { .fmh_count = ...; .fmh_keys = { { .fmr_device = / ext4 dev /, .fmr_physical = 0, }, { .fmr_device = / ext4 dev /, .fmr_physical = 0, }, }, ... }; ret = ioctl(fd, FS_IOC_GETFSMAP, &cmd);
Produces this crash if the underlying filesystem is a 1k-block ext4 filesystem:

For GETFSMAP calls, the caller selects a physical block device by writing its block number into fsmap_head.fmh_keys[01].fmr_device. To query mappings for a subrange of the device, the starting byte of the range is written to fsmap_head.fmh_keys[0].fmr_physical and the last byte of the range goes in fsmap_head.fmh_keys[1].fmr_physical.
IOWs, to query what mappings overlap with bytes 3-14 of /dev/sda, you'd set the inputs as follows:
fmh_keys[0] = { .fmr_device = major(8, 0), .fmr_physical = 3},
fmh_keys[1] = { .fmr_device = major(8, 0), .fmr_physical = 14},
Which would return you whatever is mapped in the 12 bytes starting at physical offset 3.
The crash is due to insufficient range validation of keys[1] in ext4_getfsmap_datadev. On 1k-block filesystems, block 0 is not part of the filesystem, which means that s_first_data_block is nonzero. ext4_get_group_no_and_offset subtracts this quantity from the blocknr argument before cracking it into a group number and a block number within a group. IOWs, block group 0 spans blocks 1-8192 (1-based) instead of 0-8191 (0-based) like what happens with larger blocksizes.
The net result of this encoding is that blocknr < s_first_data_block is not a valid input to this function. The end_fsb variable is set from the keys that are copied from userspace, which means that in the above example, its value is zero. That leads to an underflow here:
blocknr = blocknr - le32_to_cpu(es->s_first_data_block);
The division then operates on -1:
offset = do_div(blocknr, EXT4_BLOCKS_PER_GROUP(sb)) >>
EXT4_SB(sb)->s_cluster_bits;
Leaving an impossibly large group number (2^32-1) in blocknr. ext4_getfsmap_check_keys checked that keys[0 ---truncated---

IOWs, block group 0 spans blocks 1-8192 (1-based)\ninstead of 0-8191 (0-based) like what happens with larger blocksizes.\n\nThe net result of this encoding is that blocknr \u003c s_first_data_block is\nnot a valid input to this function. The end_fsb variable is set from\nthe keys that are copied from userspace, which means that in the above\nexample, its value is zero. That leads to an underflow here:\n\n\tblocknr = blocknr - le32_to_cpu(es-\u003es_first_data_block);\n\nThe division then operates on -1:\n\n\toffset = do_div(blocknr, EXT4_BLOCKS_PER_GROUP(sb)) \u003e\u003e\n\t\tEXT4_SB(sb)-\u003es_cluster_bits;\n\nLeaving an impossibly large group number (2^32-1) in blocknr.\next4_getfsmap_check_keys checked that keys[0\n---truncated---",

Vulnerability from github – Published: 2026-07-22 21:32 – Updated: 2026-07-27 18:31The code to parse MIME headers for display when forwarding a message (if the setting to view all headers was enabled) had an off-by-one error, allowing a single byte to be read from the memory after the buffer for the headers, and potentially crashing Thunderbird. This vulnerability was fixed in Thunderbird 153 and Thunderbird 140.13.

Mitigation
When copying character arrays or using character manipulation methods, the correct size parameter must be used to account for the null terminator that needs to be added at the end of the array. Some examples of functions susceptible to this weakness in C include strcpy(), strncpy(), strcat(), strncat(), printf(), sprintf(), scanf() and sscanf().
