Vulnerability from github – Published: 2022-05-13 01:23 – Updated: 2022-05-13 01:23

Details

The econet_sendmsg function in net/econet/af_econet.c in the Linux kernel before 2.6.36.2, when an econet address is configured, allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a sendmsg call that specifies a NULL value for the remote address field.

GHSA-23QP-3C2M-XX6W

Vulnerability from github – Published: 2025-02-04 18:54 – Updated: 2025-02-06 18:03

Summary

wasmvm: Malicious smart contract can crash the chain

Details

CWA-2025-001

Severity

Medium (Moderate + Likely)[^1]

Affected versions:

wasmvm >= 2.2.0, < 2.2.2
wasmvm >= 2.1.0, < 2.1.5
wasmvm >= 2.0.0, < 2.0.6
wasmvm < 1.5.8

Patched versions:

wasmvm 1.5.8, 2.0.6, 2.1.5, 2.2.2

Description of the bug

The vulnerability can be used to crash the chain. The underlying bug that causes this is present on both permissioned and premissionless chains, but it can only be triggered reliably with a malicious contract, so permissioned chains are much less likely to be affected.

(We'll add more detail once chains had a chance to upgrade.)

Patch

1.5: https://github.com/CosmWasm/wasmvm/commit/1151bc6df7d02d1889b8da37cf8510eaf4198eea
2.0: https://github.com/CosmWasm/wasmvm/commit/d4ff2adee44e6b9f7415a5dfbb3de745ab9b7678
2.1: https://github.com/CosmWasm/wasmvm/commit/8d44a286fabc793a2fba93752e58cd0fd5b88a2d
2.2: https://github.com/CosmWasm/wasmvm/commit/0aefa4c378457aeb3c07e7975b875be38872c56d

Applying the patch

The patch will be shipped in releases of wasmvm. You can update more or less as follows:

Check the current wasmvm version: go list -m github.com/CosmWasm/wasmvm
Bump the github.com/CosmWasm/wasmvm dependency in your go.mod to one of the patched version depending on which minor version you are on; go mod tidy; commit.
If you use the static libraries libwasmvm_muslc.aarch64.a/libwasmvm_muslc.x86_64.a, update them accordingly.
Check the updated wasmvm version: go list -m github.com/CosmWasm/wasmvm and ensure you see 1.5.8, 2.0.6, 2.1.5 or 2.2.2.
Follow your regular practices to deploy chain upgrades.

While the fix for this issue is not consensus breaking, the patch contains another consensus breaking fix and requires a coordinated upgrade.

GHSA-23WH-Q78V-XXM4

Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-11-06 18:32

Details

In the Linux kernel, the following vulnerability has been resolved:

tracing: kprobe: Fix potential null-ptr-deref on trace_event_file in kprobe_event_gen_test_exit()

When trace_get_event_file() failed, gen_kretprobe_test will be assigned as the error code. If module kprobe_event_gen_test is removed now, the null pointer dereference will happen in kprobe_event_gen_test_exit(). Check if gen_kprobe_test or gen_kretprobe_test is error code or NULL before dereference them.

GHSA-23WV-Q9M5-HQ8Q

Vulnerability from github – Published: 2025-05-09 09:33 – Updated: 2025-11-12 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

usb: gadget: aspeed: Add NULL pointer check in ast_vhub_init_dev()

The variable d->name, returned by devm_kasprintf(), could be NULL. A pointer check is added to prevent potential NULL pointer dereference. This is similar to the fix in commit 3027e7b15b02 ("ice: Fix some null pointer dereference issues in ice_ptp.c").

This issue is found by our static analysis tool

Severity

5.5 (Medium)

Details

The coff_slurp_reloc_table function in coffcode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted COFF based file.

GHSA-242H-4QQP-HPG2

Vulnerability from github – Published: 2026-04-13 15:31 – Updated: 2026-05-20 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

rds: ib: reject FRMR registration before IB connection is established

rds_ib_get_mr() extracts the rds_ib_connection from conn->c_transport_data and passes it to rds_ib_reg_frmr() for FRWR memory registration. On a fresh outgoing connection, ic is allocated in rds_ib_conn_alloc() with i_cm_id = NULL because the connection worker has not yet called rds_ib_conn_path_connect() to create the rdma_cm_id. When sendmsg() with RDS_CMSG_RDMA_MAP is called on such a connection, the sendmsg path parses the control message before any connection establishment, allowing rds_ib_post_reg_frmr() to dereference ic->i_cm_id->qp and crash the kernel.

The existing guard in rds_ib_reg_frmr() only checks for !ic (added in commit 9e630bcb7701), which does not catch this case since ic is allocated early and is always non-NULL once the connection object exists.

KASAN: null-ptr-deref in range [0x0000000000000010-0x0000000000000017] RIP: 0010:rds_ib_post_reg_frmr+0x50e/0x920 Call Trace: rds_ib_post_reg_frmr (net/rds/ib_frmr.c:167) rds_ib_map_frmr (net/rds/ib_frmr.c:252) rds_ib_reg_frmr (net/rds/ib_frmr.c:430) rds_ib_get_mr (net/rds/ib_rdma.c:615) __rds_rdma_map (net/rds/rdma.c:295) rds_cmsg_rdma_map (net/rds/rdma.c:860) rds_sendmsg (net/rds/send.c:1363) ____sys_sendmsg do_syscall_64

Add a check in rds_ib_get_mr() that verifies ic, i_cm_id, and qp are all non-NULL before proceeding with FRMR registration, mirroring the guard already present in rds_ib_post_inv(). Return -ENODEV when the connection is not ready, which the existing error handling in rds_cmsg_send() converts to -EAGAIN for userspace retry and triggers rds_conn_connect_if_down() to start the connection worker.
